Injora RC Crawler Inserts: Unbiased Testing and Comparison
ฝัง
- เผยแพร่เมื่อ 20 พ.ค. 2024
- This is it. This marks the end of foams for crawler tires.
Foams still had a chance when it took $100+ to get a set of inserts...but with Injora selling them for $20 for 4....THE FIGHT IS OVER!
I test the red (hardest) and blue (medium) inserts from Injora in this video, but they also just released a softer spec that is green. I will pick some of those up very soon.
Are there better inserts out there? I expect so. But are they worth the HUGE price difference? Hard to justify.

People just like to hate on Injora
I love injora
They had a bad reputation for awhile, but seem to be turning it around.
It's just a label brand man. I doubt they make anything.
Injora has never really let me down
Well injora kinda seemed like goolrc, they just found generic Chinese products that sold for super cheap all over on sites like AliExpress and eBay and slapped their name on them and sold them for more. Now they seem to be coming out with their own stuff though that’s halfway decent.
Injora is finding its way into almost all our crawlers one way or another. The blue inserts are awfully stiff unless it's a heavier rig. We just started trying the green ones and they're far better for light to midweight crawlers. We're sold.
Also they fit the new Toyos from Proline perfectly!
Nice! I have a set of green ones on the way.
Try modifying the blue ones like I did - makes a HUGE difference.
Great presentation Troy. I love how you always make a science experiment out of some of your product reviews. The biggest benefit to me for these gel inserts is that they keep the sidewall a bit more rigid than the foams and of course the lack of breakdown and deterioration you get from foams getting wet. I will be ordering a few set of the green and blues in the near future for my rigs! Thanks for the in depth review buddy! 😎👊🏼👍🏻🤗
Thank you! I am just curious and having fun!
Glad to see someone else giving props to Injora on these inserts. I’ve tried the blue and the green sets now and they are awesome. You can NOT beat the performance at this price point. Awesome video man!
Thanks! I have a set of green on the way as well now.
Also I think a hybrid could be very interesting. Like a two stage foam only having a foam on the outer portion to get the deformation wanted to grip and the antifoam for sidewall stiffness.
I really like that idea!
These are already available as well.
Antifoams are a 3brosRc insert. Not to be confused with anything else. 3d printed inserts are what your talking about.
@@redndeyes um..... I'm confused. Lol. There all 3d printed inserts. Call them what you will.
Been watching your content on the DL, this video made me sub because of what you said about online. You bought and cut inserts thats what I need to watch as a newbie. Happy 2024 my friends.
Thank you for the kind words! Glad to have you as part of the team!
Excellent video ! Good facts and research. Truck is running great. This vid has helped my decision process in the inserts.
Awesome! Glad I could help!
Great video, very informative. I have the ascent and was looking at these inserts. Couldn't have been more helpful content, think I might go for blue or green inserts.
Awesome! I also just released a video on the green inserts - testing them on my Ecto that is slightly lighter than the Ascent.
Nice !!!!!
I love the innovation in this hobby!! I do not have a crawler I have never had one. I've always been interested in them maybe someday.
🤞
I was always skeptical about crawlers - until I went out with a group. Hours of fun!
It's like crack.
can see the usefulness of these inserts was great to see a comparison and test most interesting
*🦘Au🦘💯full view always📺thumbs up👍enjoy your week😎*
Thank you Billy!
OMG I just watched a 1/2 minute ad for a scam and then another 30 second ad before your video. I gave up on the last video because it started with a 5 minute video before a 3 minute video. Thats CRAZY
Unfortunately, TH-cam has turned off my ability to control that any more.
The only control they give me is IF there are mid-roll ads (which I leave off).
Thanks for this test 👍
My pleasure!
Thanks for doing this video!!
Glad you like it!
Awesome video, thanks for testing them
Glad to help!
Great video bud! I have really wondered about those exact Injora tire inserts. Very cool. 😎👍
Glad I could help!! I highly recommend them!
I have 3 sets of these and they really help and they do help the tire hook up!
Great! Thanks for the feedback.
What spec do you have, and on what vehicle?
I’ve got the blue ones “mediums” on a 10.3 Jlu weighted at 12.5lbs and wrapped with proline Toyo open country R/T’s 4.75. I’ve got the green ones on an ultra light axial 1.9 wraith and those have the red compound falkens by vanquish. Again, they hook up and give those much needed sidewall support. Hope this helps!
I think its nice too have a good alternate against the double high prized 3D foams from the premium brands ,thank you Injora.I hope for 2.2 3D foams for my Bomber too.
oops, at 8:35, don't forget about weight transfer to the rear when ascending, great video so far. Love you demeanour, aaaaaand subbed!
Good point! Thank you!
Right on thank brotha!
Great video, loved the in depth that you did,been waiting for this video,I have used your opinion quite a bit and have always been satisfied, as you said everyone is a little different in some way,they can be tuned by a snip here or there,which ones would you start with on a trx4, has 2speed and diff lock
Thanks Thomas!
Does your TRX4 have any brass on it? I would be curious how it's weight compares to this Ascent.
If it is a little heavier (which I assume it is) I would go with the blue inserts. I think those would probably work really well as-is.
Easy link for you: amzn.to/4b2B7fZ
@RoadsideRC as always I appreciate your opinion, only mod is it has aluminum axles
Great timing. I just ordered the blue ones last week. I was tempted to get the greens but decided to start with the blue. Im curious to see how they do when broken in and in warmer weather
Agree! I will get some miles on these and see how they hold up!
I’ve got the green one they are a bit thin so now I’ve got to get new tires which is a good thing great review love from across the pond 🇬🇧
Thanks! I have a set of green on the way as well.
@@RoadsideRC they are soft
I have them they aren't big enough for proline hyrax 1.9's, but i just "shimmed" it out with thin upholstery foam, and its now really good. I have injora rims as well.
Interesting! Thanks for sharing.
Foams make a Big difference! Good video.
Yes! Thank you!
Good review 👍🏼 will get some for my cheap crawler 😅👌🏼
Thanks! I think they are a good choice!
@@RoadsideRC I may tell you how the blue ones perform in a few days . Thank you for your awesome content on your channel.😁
For close to the same price you can get YZZR inserts which have over a year of testing and tuning to get them where there are today. They have helped keep me on the podium on the East coast no one has better sidewall stability 🤘
Thanks for the tip!
What do you think makes them better?
@@RoadsideRC for one each insert is custom fitted to the tire then the sidewall stability is top notch with the perfect amount of squish on the contact patch allowing the tire to function properly and not act like flat tire which is what we saw with most foams my opinion may be a tad biased as I helped test for the company from day one but I have been extremely critical and they made improvements using our results we also tested using 40 different tires of all sizes and brands and in every kind of weather and condition. Definitely put in the work to get the product where they are today and I highly recommend trying them out. The soft and super soft have been My go to on my competition rigs all around 5 pounds
Great information 👍🏻
Glad it was helpful!
I’ve been running the blue for a bit now and really liking them for $20. I have a green set that just arrived.
Nice! I have a set of green on order!
awesome testing, cant complain for the price
Yes! I agree 100%. Hard to not try them with the price.
As you drive on them they get softer. I have a set of blues and I love them!
Great to hear!
I live south of Phoenix in Arizona where it’s pretty damn hot. It doesn’t seem to make them softer, I have a very heavy, full metal TRX4. The blues were way too hard out of the box. I am from Oregon so I understand cold rainy weather. I can confirm these inserts do not change underneath heat. Not enough to avoid cutting all the ones you think necessary.
5 Star rating!
Would you recommend blue or green for the trx4
I am interested in seeing the green ones now ! And another question do you have a link to the scales that you use to weigh your rigs thank you again for another great video !
Hi Kirby!
The green ones should be at my house this week!
They have upgraded the scales I use - now offer a bluetooth version: bit.ly/4b70ixE
These scales have been worth EVERY PENNY for me.
@@RoadsideRC thank you !
A friend of mine has a blue set and he says they're really good. Myself i use squid inserts on both my crawlers with vented wheels/tyres and they perform great
Nice! Glad you like them!
Do you think they would work for a short course 1/10 if I used the green to get more traction with my 2wd ? I hate the foam in some of my older tires?
I do not. (1), they are the wrong size, and (2) they are heavy.
Love the info.
Glad it was helpful!
I have a set of the green ones for my TRX-4, and they seem stiffer than the foams I had in my tire before. I'm not super familiar with foams and their weight ratings, but the greens seem perfect for me.
Nice! I have a set of green that should arrive this week!
@@RoadsideRCI like how these liners give a rounded sidewall. My goal is to get more accurate steering, without losing forward grip. Its nice that my wheel rings aren't gonna get nearly as much rock damage because the correctly shaped sidewalls. Greens for stock ascent no brass. They do break in like regular foams, and cold does make them stiffer.
Injoras new brass heavy wheels are absolutely sick! I have a ton of injora stuff on my gen8. Shes a heavy girl. Everything ive been able to buy in brass I have on it, and then the rest is replaced with aluminum. I just finished it up by putting 2.25 oz of weight in each front tire with harbor freight 1/4 oz wheel weights. Takes 11 evenly spaced. Problem now, is that i do need something like this. The foams in my hyrax predator compound have had so much deflection on sidehills one tire actually came out of my beadlocks.
Do you think there is enough flex in these inserts that I could put them around the inner beadlock ring plus about 1/4" for the weights? Or do you think they wouldn't fit, or grow to a way bigger size overall?
I am honestly not sure they would fit. It is a tight fit just getting the normal beadlock center ring in there.
Hi Troy nice video
I belive that I'll order soon an ascent.
Thanks! The Ascent is a really good truck!
I have the Blue Ones in my Wife RGT EX86010-CJ (almost 4 quilos heavy) and whit the Louise CR Champ tires in wet (this tires are bad in wet) they performed amazing ❤❤
Awesome! Glad to hear it!
For my experiênce they are a Great deal!!!
Here in Portugal i buy 4 Injora for €20,00 but if i whant a 3DPRINT i need to Import from UK or USA and 4 will cost €100 so...
I have found the red ones to be perfect!
Interesting. How heavy is your truck?
@@RoadsideRC less than 10 lbs, but it's a scale tow truck. The reds support a tow load perfectly.
Im new to the hobby so I was wondering taking on and off the tires do you need to glue the tire to the rim?
The factory wheels are glued, yes.
But, most folks quickly move to aluminum beadlock wheels. They can be unassembled and reassembled over and over.
@@RoadsideRC Thank you for the help, it really helps me.
An interesting potential is wet performance. When the foams in my TRX4 get sopping wet from the river romp -- the whole rig get ALOT heavier naturally in a good loaction - - grip is improved, etc. It can be a doulbe edge sword though bogging down and eating batteries moving all that added weight. These presumably, like inflatables, would not suffer same issue as soaked foams.
That is correct!
I like 24th's, but interesting vid all the same.
????- I wonder if there's an additional difference with venting between these and foams. With venting on the tread face, foams still let the tire 'inhale and exhale'. I wonder if the non-foams block the vent holes when punched on the tread face, being they aren't porous like foam. Might be a cool test to see the difference in venting tread face vs side wall vs ???.
Thanks Troy. Enjoyed you're style of vid and relaxed personal manner. I'll check your channel for 1/24th stuff.
Cheers
Bert the Weldor
Hi Bert!
So far, no issues with the venting. Seems at least 1 hole is always open.
They recently released these same inserts in the 1.0" size. I am testing some now on my Ascent 18.
@@RoadsideRC Nice! I'll keep an eye out for it. I've got a DIY, no printing, no hi-tech idea for inserts that are pretty out of the box but easy for any 'no-budget' person to make. Just need to get to it and test.
Idk its all catch 22. I personally like my tires folding some cause it keeps the tires from sliding out and holds it in place better which leads into less chance of sliding into a gate. But with that I have to really learn what my truck roll point is. Not having the fold on side hilling does come with cons as well
Makes sense!
think the size thing is that is pushing the tires out and not leaving an air gap.
like a 4.5 insert in a 4.75 tire..
you end up with the overly round top. instead of nice and square.
Interesting! Most folks were complaining that these were too small....
Too big is easy enough to take care of. I'm not scared of modifying them!
I bet the green ones will be what you want uncut. Sidewall deflection seemed to be zero, and it crawled over everything in the video without hesitation. Not sure what folks are complaining about, other than that complaining is the default setting for a lot of folks online.
I have a set of green on order! Excited to try them!
Tory, going to get some of the blue for my Axial Early Bronco. If I like them I built a gmade r1 that might get some also. Keep ya posted.
Nice! I have a set of green on the way as well.
Maybe do another video on the green ones. Would love to know how they do.
@@user-xe8dd1yv2x Will do!
Been busy so I just ordered a set of blue for my Early Bronco. Will be here Monday.
The rollover with the foams is actually a good thing… that’s what the sidebiters on the sidewall are for. You are still getting good traction with the tread lugs on the sidewalls utilizing all the available tread on the contact patch. I have some 3D printers… but I’ll stick with foams. I think they wouldn’t hold up on a massive roller over. Would tumbling down a 10-20ft. hill rip up or break the plastic inserts on a heavy rig
Interesting thoughts!
Let me take them one at a time.
Sidewall: fun fact - I actually work in the 1:1 tire industry. I can 100% tell you with confidence that the sidewall is not there to accommodate rollover. With the way these tires are molded, it is similar in 1:10. Excessive rollover is never a good thing for traction.
3D printed durability: these Injora inserts are not 3D printed. They are molded from a very pliable material. There shouldn't be any durability issues.
Also - as I showed in the video, I had 3D printed some inserts myself. It isn't from PLA or PETG. It is printed from TPU. These inserts have been through many miles (and many crashes) without any degradation.
Don't over think this and hold yourself in a box! Go out there an experiment! If you already have a printer - then the file I used was free. Just buy some quality TPU material!
very good to know
Glad to help!
I need them so much for my scx24 build, I hope they make them
Agree! I hope they come out with more sizes.
They should get softer as you run them more. Also notice in the cold they do get really hard but work great indoors and in the 45° and up temps
Thanks for the tips!
I can’t remember if you have done it before but the yzzr inserts are good for a reasonable price like $35-$40 for a set and squid inserts are also around the $50 for the set. The ones that are extremely overpriced is the 3brc. I have a set of squids and 3brc inserts and i like the squids better. I might try the yzzr’s next.
The price is always what has held me back. $20 for foams...$20 for these - and double that, at minimum, for the other options.
@@RoadsideRC i understand that. I got the 3brc ones just to see what all the hype was and wasn’t impressed on how they are mainly made for PL tires and at $75 for a set plus tuning rounds and tuning rings . When i seen the squid inserts at $50 for the set so basically the same price as CI or PL dual stage i gave them a shot and don’t regret it one bit. Going on 1 1/2 years and the squid’s still preform like new.
Nice over view Troy. The thing I was wondering about these tire inserts, is the fact that they have the corners chamfered. Therefore not filling the tires I have been wondering about that. Although it doesnt seem to have too much of an effect on the run. Did you notice anything?
I watched that as well. Didn't seem to have an impact at all.
Love the treal wheels
Me too!
@@RoadsideRCYou all have good taste
What are the wheels that youre using? I love the color on them
Hi there! I agree - these wheels are GREAT.
This is a direct link for them: alnk.to/5jkDGFE
@@RoadsideRC Thanks!
Awesome content man im loving it 🤙🏼
Hey man I just bought the new ascent fusion gonna get injora turbine 1.9 beadlock wheels they are -10 offset and gonna keep the awesome stock tires that come on the ascent u reccomend the blue silicone inserts or red im in south Florida its hot year round jajaja
And u think i will have any issues running that particular wheel, tire combination
Does the -10 offset affect the performance much besides pushing the wheel outward ??
Because i know stock offset i believe is 0 on the stock beadlock wheels that come on the ascent fusion ??
Your opinion would be great man
Thanks
Hi there!
You will either need the blue or the green Injora inserts. The truck is waay too light for the red.
I just installed the blue on the front, and had to trim some of the ribs in order to get the tire to flex like I wanted.
I think the wheel you want will work just fine. Good luck!
@@RoadsideRC man thanks i just noticed they have to sizes of the same silicone u think they will soften up over time ? If soy i will go with the blue
They have two sizes
-106-108mm(4.19" OD) 1.9" Tires
-118-122mm(4.75" OD) 1.9" Tires
Im gonna use the Stock tires on my redcat ascent with injora beadlock wheels witch size is what im supposed to go with ??
@@RoadsideRC thank u man great point im guessing the new ascent fusion with the carbon frames weighs less than the regular ascent so i feel the green would be great although the advantage of the blue is that i can cut them maybe wait a couple months they might get “softer” with use
U think the green ones will squash too much ?? Thats the real question even though like i said its the “fusion ascent” has less weight than the regular ascent
Also what plug n play charger u reccomend for the 1500 3s lipo from amazon
Im currently lookinh at 2
-Spektrum S155 G2 1x55W AC Smart Charger
-OVONIC Mate1 Lipo Battery Charger 1s-6s 100W 10A
@Senditjp247 Hello - yes, the green may be too soft...but not sure yet.
This is the charger I recommend:
amzn.to/4a4JOFn
@@Senditjp247 You need to use the 4.75" ones for the Redcat tires
I think there is a correlation with to much squish and lose of grip. you dont want the tire to deform and fold when moving you need the tire to bite and with those inserts the bite is harder then if it was softer.
A balance is very important - I agree!
They also take two battery packs to season the inserts I found sidehill is crazy good
Awesome! Thanks for the tips!
There's another company that came out with the inserts like that but they're wider and they're on AliExpress is there a way I can send you a link to it because the ones I got there are 16 dollars for four and I have four different stiffness blue red green and pink
I don't shop on there very often - thanks for the heads-up!
What is the name of the body you use there ? Nice video mate😊
This is the Redcat Ascent - it is the factory body.
I got 8 pairs! 4 blue 4 green. Blue on the front green on the back.
Nice! Makes sense to me.
I have more coming in the mail as well.
I wonder if you stored your crawlers with tires on the ground; would that cause a permanent deformation of the antifoam? It would appear that it would not, but I'm still curious.
These have sat on my garage floor, in sub-freezing weather now....with zero issues.
From my experience, it’s worked better running a softer foam/anti foam in the front. My main truck is right at 5lbs and I’m running super soft anti foams in the front and soft in the rear, made by BAMF. I’ve also had really good success with 3BRC and SL3D squid inserts. I feel like the green injoras would be a good cheaper option in a lighter truck and if you spend a couple extra bucks you can get some customized inserts in the future if you want to upgrade.
Interesting! Thanks for the feedback!
Are they available in different od sizes or just the one from injora
So far, just one dimension. BUT - if they are popular, I can imagine more would be on their way.
@RoadsideRC I hope so they look like a good deal. I do run a smaller 1.9 on one rig and a fairly large 1.9 on a different one so it would help
Since these silicone inserts seem to increase the OD of the tires when inserted, folks who compete in Scale 1 comps may want to use tires with a smaller OD than the max 4.2"/106mm permitted in that class, just to be sure these inserts don't push the OD beyond spec.
These inserts are only for 4.75" tires - not applicable for Class 1 tires at all.
i am curious it can stretch to 2.2 wheel?
It can not. It is a tight fit over the 1.9". I assume they may come out with other sizes if these are popular.
Yes! I stretched my greens onto 2.2" wheels and use mickey Thompson 4.70" tires from rc4wd and it's a blast.
Puedo hacer lo mismo para ruedas de carretera? En 1/10 . Busco que no inflen
Aún no los fabrican para ese tamaño de neumático. ¡Pero creo que funcionaría!
I was always dedicated to Crawler Innovation’s foams until I tried the SL3D squid inserts.
Nice! Thanks for the feedback.
I have them are good
You can also use hair donuts
Nice video! I bet it’s the cold that makes the plastic hard. You should have bought the green ones and have them as winter spec! 😅
I have green ones on the workbench now!
@@RoadsideRC interesting to see the outcome of a new test!
When weighing those corner scales you should have installed all the same. Took the old foam and tires off because that's going to mess up your overall weight of the vehicle if you have two different types of tires on there and wheels
Yes! Of course it will!
I think the reason the first lot of snips didn’t work was that it was just sitting on the sniped parts, so if you remove the whole little piece it would work better.
You might be right! I looked closely, most were folded over or missing each other, but maybe some impact.
È possibile montare gli inserti injora senza gli anelli centrali?
No. È necessario l'anello centrale affinché il tallone tenga il pneumatico.
Since there is only 1 od size what is it?
It matches the 4.75" common tire size.
So i have a 3d printer . Should i make my own or just pick up a pack?
Hard to go wrong either way.
I LOVE to 3D print things, so plan to do more of that for testing as well.
Spool of TPU: $20-30.
4 pack of these: $20
It is a toss up.
A spool of tpu could fit out multiple vehicles and let you tune the hardness through the number of walls.
My blues are cut to match my 5 pound rig works great
Nice! Glad you like them!
What about weight with a batty
Good question! I run a small 3S, so it has a small impact.
Nothing works like a crawler innovation foams.💪🏻🤣😂🤣
I hear a lot about those!
Crawler innovations dual stage will never be beat by a printed foam….. ever.
Good news! These aren't printed! ;)
Your wheels are overall 27mm wide. That is why you have no issues with sliding inside.
Since this video, I have put the red in another set of wheels - also no issues.
Injora makes great stuff for reasonable prices
I have had good luck with some of their products!
Looks rock hard to me. Cheap isn't always the anwer.
Did you watch the video? They are tunable for the stiffness you want....and they offer a softer green spec if needed for your setup.
It really sucks but you are right for the money you can't go wrong and even if making yourself you just won't do it cheaper than China, ever. As far as unbiased videos I have always had a difficult time believing certain channels or people especially when they are directly compensated from those companies or sent free gear. They never seem to come up with anything negative to say about the product because they would 𝙎𝙏𝙊𝙋 getting anything from that company and others would hesitate to deal with them out of fear. Not saying that's you whatsoever just saying it's a thing..
Thanks!
I have been part of multiple deals with companies. The good news - literally only 1-2 have ever pressured me to only say positive things. Actually, the more critical I am, usually the more appreciative they are! Seems the good ones really want the feedback.
It would be cool if they give you instructions on how to cut them to make them for a lighter truck I mean anybody can cut them, but if they had instructions on how to make it less stiffer for a lighter truck, that would be kind of cool
Good idea!
I would just buy the greens instead of cutting them... IMO
You mean like this...th-cam.com/video/ajIwgZ6TroI/w-d-xo.html
:)
The green might not be the right choice either.
When you crawl up a hill the weight will shift on to the back
Yes it does! Of course, still only a small percentage of it moves.
Nothing beads the good old Proline Krawlers Predators with the red dualstage from Injora. Just don't vent your tires. Its not beter.
Yep - you and I disagree there. I 100% suggest that folks vent their tires.
its a conspiracy. manufacturers are making larger tires with weak sidewalls to capitalize on making inserts; yet another thing for us to buy at very inflated rates... which we will pay! Well, that's partially what I believe, but if you watch carefully, there is only so contact patch that actually occurs vs the profile of the tire; there is a relationship, but high profile tires are so unnecessary. imagine a tire with less profile, similar contact patch, and no fold to the inside, but only on the outside to create a stable contact patch on sidewall and no need for inserts.
Hmm. A conspiracy? Interesting.
Dude, you literally replicated what you could have done with foam by cutting the injora inserts. JUST USE FOAM.
...and that would have helped the sidehilling, water retention, and breakdown over time...how???
