- On this episode of Rock Rods Tech it's Trailing Arm Suspension Explained by Jake Burkey. Jake will be teaching you all that there is to know about Trailing Arms and why you need trailing arms off road or on your race rig. Jake has also released his own riot signature series trailing arms built by TMR Customs. They thought of everything with these new units making them some of the strongest ones on the market. Jake Burkey Riot Buggy won a lot of races on these and so has Bubba Bacon. The Jake Burkey New Buggy will be running these exact Trailing Arms as well. He will even show you how to assemble them at home. Be sure to let us know what topics you would like to see covered on the next Rock Rods Tech Tip. Hit us up if you need trailing arms or any other off road parts for your rig at the busted knuckle off road parts and accessories website- www.bustedknuckleoffroad.com

Another great video. Always enjoy having Jake explaining things in a simplified manner. Keep up the good work.
more on the way, i think we will do some driveshaft tech next
Dam Jake that's some serious welding that's some of the best I have ever seen!
They are decent
Rusty Wells if you've ever seen jesse james lay a weld you would shit... welder of the year how many times?
Dude can weld no doubt
I'm moving from Northern Idaho, to Summerville SC. I will be stopping by you shop. Great build!
heck yeah stop on bye!
Awesome video . Good learning channel, top of the line improvements. Thanks for the teachings!!
Thanks for tuning in
Great video Jake I'm thinking of getting a better suspension for my truck this gives me a lot of ideas thanks Jake keep up the great work
What kind of truck?
i love your channel and watching you explain stuff. i understand your reasoning for creating the shock mount brackets. But having the shocks mount above the center line of the pivot points, makes the link want to twist, which puts added stress on your heim joints, uniballs, or bushings that are being used at your pivot points.
why not spend the extra time, figure out where you need/want your shocks mounted ? And then build your links accordingly with shock mounts below the pivot point center line, eliminating the added stress of them wanting to twist. Maybe that's why some of those 3/4" bolts are breaking ? The aluminum rod insert is awesome ! Adds minimal weight but makes it bullet proof
That is why we built them the way we did with the uniball up front and massive heim, clearance is important to us as well as adjustability so we can make sure the shocks are packages correctly. These exact arms have been beat on with numerous bouncers with zero issues and a lot of podium finishes.
Thanks for the info and nice welding!
Thanks for tuning in
New subscriber. Because my trailing arm.came loose on my old Pontiac. You are so smart!!
Trailing arm on a Pontiac?
Dude thats a hell of a design for trailing arms right there. Badass!!
They work well
Man you are in it to win it, quality guy here. Love this stuff
just trying to make sure everyone gets the most out of their off road rigs
Wealth of knowledge, super impressive.
Jake knows his stuff that is for sure
I Love this video, because I am going to build a Baja Bronco and I want to anywhere and your a big help in that build. Thank you.
We are building a Bronco Prerunner.
Very nicely explained and with high quality super strong product.
A lot of race have been won with these
Dude those trailing arms are GNAR!! And of course you've thought of errythang, only the best
They help make a race winning setup!
I've been trying to replicate these dirt devils in a game I like for a while now. Since, I could never hope to afford one. I just like how agile the suspension makes them. It's so fekkin awesome!
they are a ton of fun
Would love to see a documentary on the frame build for a rock bouncer!
That is top secret! lol You are better off just buying one of our production chassis
www.bustedknuckleoffroad.com
thank you information jake. thank you video matt
Sure thing!
Nice skill jake . Thank you video matt
Thanks for watching!
cant wait to get my hands on a set of these!
They are worth it
I hope your taking this year off and putting all of this tech in your new buggy and come back with a vengeance we need you brother.
That is exactly what is happening.
Looks like you know what your doing. Bad ass trailing arms.
they work well
Amazing work and product.
They work well
Thanks Jake!!
Learning a lot from your vids,
Glad to help!
Wow you can weld my friend.
Im building a light weight offroader. With a gsxr1000 engine. Its a nissan patrol now and want to make something like you. Only less heavy.
Thanks for sharing this helps me.
they can be made lighter duty
Nice fitment great explanation.
Thanks!
Very good video, a lot of info! Thank you
glad it helped
Thank you. Usually only see low rider people with air bags explaining trailing arms.
glad we could help
Yo Jake it’s Eric, I use to work with you at Oreillys back in the college days. I’m glad your killin it. Looks like you stayed with it and still doing what you love. Who else would know that you built that long arm kit on your Jeep in your apartment parking lot. Ha. Surely you come out here to Wind Rock, maybe I can watch you run that buggy with these new arms you’ve designed.
he is buggyless at the moment, been building them for customers and his has been on the backburner.
Great video.
Thanks!
Thumbed up all the way 👍
Thanks!
Estou impressionado com os acessórios que existem para este tipo de suspensão mas gosto muito dos vossos vídeos com os polares, um abraço vemos no próximo vídeo.
obrigado
The stuff your doing is out of my full comprehension but after watching this video gonna watch more of your video's to get some ideas for a go kart for my son want to make him something that will make memories for a lifetime.
People build mini rock bouncers for kids
18:45. Sick crocs!
Jake is always rocking them
Holy heim joints Batman!
big joints FTW
@@BustedKnuckleVideo This is great, thx for the vid!
Love these videos guys! Lots of information to get my head around..
If I want to mount my shocks onto my trailing arms do the arms need to be parallel to the chassis frame? I’m tight for space and I was hoping to kick my arms out at 10 degrees to help with triangulation.
Thoughts?
they do not have to be parallel with the chassis we triangulate ours also
By the way ! Your an Awesome Driver Jake.
He does ok, he better get his new buggy done before he forgets how to drive lol
I had a similar problem with mud build up. It’s a pretty redneck solution, but I filled it in with clear silicone. Yours is better lol, but it worked.
you filled the tube with silicone?
When you switched to 1/4" wall (from .188") on the 1 3/8" DOM. I assumed you also bumped up to 2 1/2" O.D. Am I correct? Because 1 3/8" x 1/4" wall (if there is such a thing) won't accept 2" OD aluminum round stock inside it. Could you clarify this for me?
Love these videos, very informative. I wish I would of had access to these 10 years ago when I was building my rig. Learning on the Pirate4x4 board could sometimes be brutal.
That is correct.
That's a beast... U rock
they work well
First off, awesome vid! You guys make some great and informative vids that are easy to watch. Thank you!
Now the question...I'm new to suspension theory but in a trailing arm setup how are you controlling pinion angle and axle wrap? Is the panhard pulling double duty and taking the additional stress? Do trailing arms use a upper arm of some sort as well?
If the panhard is taking the extra stress involved, how much more beef do you have to build into it?
there is no pan hard, it is a double triangulated 4 link with the shocks mounted to the lower links.
Ah got it. Thanks
absolutely outstanding work. I want to beef up my ZJ jeep suspension to be able to drive it faster trough the desert. but I Don't think I can fit the Shocks like that unless I punch a hole in the rear seats... I really wonder how
you could always do cantilever shocks
Great video could this setup work for a backhalfed prerunner
absolutely
Necessity is the father of all invention
Truth
I feel like a mail man going for a walk! Lol looks practical and strong
all the travel with a smaller shock FTW
Busted Knuckle Films makes good sense, just have to beef the shock and springs up, since you lose some of the mechanical advantage outboard mounting provides.
Great ideas, addressed important and common component failures, with problem solving, down time prevention, structural improvement and ingenuity.
Great info 👍 I am curious if this step up would work on my stock LJ frame or would I have to "back half" the rear into a tube style frame? Sorry I'm still learning and don't know all the terminology yet! Thanks again!
It would take some custom fab work to make them work for sure
It would take some custom fab work to make them work for sure
What are you thinking would be some of the challenges? Thank you for the reply.
To anyone welding (especially mig) near machined parts, particularly with the inside of those uniballs exposed... anti-spatter spray (not water based) is your friend, or jam an old welding glove in there.
-welder/fabricator with over 30 years in the trade.
Anti spatter FTW
1 question Jake,
about the giant joints with the 1" bolt, how thick should the mounting brackets be? Would 5/16 be enough?
I would say 5/16 to 3/8 depending on how heavy your rig is.
Nice!!
they work well
There's such a clear advantage to trailing arm suspension over regular 4 link in rock bouncers. Like Bubba Bacons buggy it is so much smoother and faster since he went to trailing arms
I don't understand why more racers haven't went to trailing arms.
They are difficult to package. This kit makes it easier though. Bubba Actually runs these exact trailing arms.
BustedKnuckleVideo ok so what is the actual advantage of the trailing arm vs the standard lower link? I get that you can get a X 1.5, X 2 or whatever on travel length for your shock, but gimme another benefit... I’m not dissing the trailing arm, I’m just not seeing another advantage. Plus ya get the link wobble jake revered to
It's all travel and smoothness. It's the reason pretty much ALL pre-runners use them. They can get 20+ inches of travel while being smooth and controllable at high speeds. It's what makes your landings bearable when jumping and woops controllable. The same principle is used on independent front ends. Takes less shock to get the same travel and is softer. Kind of one of the reason most new stock trucks have gotten away from a solid front axle.
brilliant
Jake knows his stuff no doubt
Great idea. I just wonder about the cost and can you just buy the joints without the tubing.
Yes here are the components and pricing- bustedknuckleoffroad.com/Trailing-Arms_c296.htm
I’ve watched this video a couple times. I pickup a bit more each time. I have one big question though. I’ll be using tmr archetype trailing arms or maybe riot buggy arms. How long should I make the trailing arms? My front 3 link has 40” links. I chose 40” because I’m on 40” tires. It’s a Rock crawler / decent amount of high speed stuff. How long should my trailing arm be? And do the uppers on a trailing arm system need to be the same like you would want on a 4 link?
This video helps explain more about lengths and geometry- th-cam.com/video/BTWZgVx8Y6o/w-d-xo.html
Thinking about running this same set up on a 2500 diesel pick up. Just to be different. Do you think it will hold up for towing a bumper pull camper and daily driving. It will never pull a 5th wheel or goose neck. Due to truck height.
It would be a lot of work to go from leaf springs to trailing arms and to our knowledge these have never been used on a truck.
Good basics
The top racers in SRRS all run trailing arms, Bubba Bacon is #1 this season in both SRRS and Pro Rock and he runs these exact trailing arms.
How do the Brackets slide back and fourth for the adjustment of the Shocks if they're welded to the Trailing arm? I was watching but didn't quite see what was adjustable.
He was saying before you weld them to make sure you adjust them where you need them on the arm, most kits do not have this adjustability
its tabs and a piece of tube...lol
I was thinking it would be interesting if they made the bracket a wrap around tube on the trailing arm for almost infinite adjustment and a clamping system to prevent sliding. Would have to make a key way on the trailing arm and the mount to prevent it trying to roll on the tube.
@@onemeangreen interesting design theory. The size of the key and key way needed to withstand the force would excede the thickness of the tube itself. Or get it so low it would loose its structural integrity. But it would be interesting none the less.
@@chrislangdell117 I was thinking a key way cut into the bottom of the mount that runs along the top of the tube, then a key that's tigged along the top of the tube so the mount could slide front to aft. The mount would be a wrap around that clamps down and the key would prevent rotation. Just a thought. Great video.
How do y’all keep your rear end from moving off center left and right when using trailing arms? Some kind of sway bar?
Tyler Gillespie uppers and lowers are triangulated to hold the axle in place
BustedKnuckleVideo thank you very much
Your first MIG welds, after the tacks, looked like stack of dimes from a TIG, are you doing cursive "e"s or "i"s for aesthetics or is this your preferred MIG technique? Great video, very informative…thanks!
just preferred technique
Looks great...
So I’ve been seriously looking at building trailing arms for my 80 squarebody. Would this be a decent set up for a more daily driver or is this strictly off-roading purpose???
I had an 06 f250 with trailing arms instead of the conventional leave springs and absolutely loved the ride quality.... now, I understand that daily driving this set up might be harsh for this setup because of the replacement of rubber bushings but I’m curious as I’ve never seen this set up on a daily driver
We have never tried it ona daily driver but it should work.
Hey jake we are in the process of redoing our Jeep trailing arms and was hoping to see if this setup is available to work with a wrangler!
Also where did you get the 1.75 Heim love that thing it’s massive
we sell the kit and with some fab work they can be used on a wrangler
Any worries about the galvanic erosion between the aluminum and steel or have you done something to address that?
not worried about it
Thinking about using some of your trailing arms on a prerunner im building with my 13yr old. 66 ford TTB dana50 and 14 bolt. Turbo Ls/4l80e/205
Should work perfect 👍
Cool guys didn't know
they have been a game changer for the rock racing scene
What about galvanic corrosion between the steel and aluminum? Ever cut one in half after being together for a while?
the two parts don't need to move and are too thick to fail from corrosion so should be a non issue
Looking at the modulus of elasticities, you could use 6061 rod inside the tube instead of 7075 and retain 96.15% of your resistance to bending
modulus of elasticity of 6061: 10,000
modulus of elasticity of 7075: 10,400
(the steel will yield and bend a significant amount before either 6061 or 7075 come close to their yield strength, especially since the aluminum is mainly there to force the steel to maintain its round cross-section)
why compromise strength to save a few bucks?
@@BustedKnuckleVideo Because it's not a few bucks when you're talking 7075. Its probably half a grand, and that money could be better spent elsewhere.
Hey jake im thinking of a long travel kit for my 4wd tundra with a 4 link. should i go for something quite this beefy if im only going to max push 500 hp? and im going to be limited on my front travel so i shouldnt be pushing more than 20ish inches
These would work for the application but are probably overkill
Hey Jake your a tru professional so hope you dont take my comment as rude
Where'd Jake learn to weld? I'm quite impressed.
practice
What about stability? Is it more stabel to put youre suspension on the trailing arms or is it more stabel on the axle ?
shouldn't change stability
I have a 1995 GMC HD which is 10 lug it's a welding truck so I'll be down in the woods with it sometimes but not being extreme like what you guys do I want to put a suspension close to what you did have you did anything like this with a 3500 HD I am a fabricator and I will build it I'm just researching the internet your videos been the best yet thank you for your video I'm trying to copycat a little bit of a Kenworth does the upper trailing arms at V into the top of the rear end have to be the same length as the bottom ones
the lowers are typically longer than the uppers
Is this strictly an off-road application or could it be used in a “adventure truck” that would see road as well as off road use?
I would say it's better for a mostly offroad vehicle
Is it the same as what they call “traction bars” in 4x4 trucks with leafspring suspension?
not at all
1967 C10 with Dana 60s front and rear I'm in the middle of building a motor 350chevy.
.030 over balanced rotating assy.kb pistons edelbrock top end shooting for 435hp
sounds awesome
You should build a lift kit for a Polaris rzr 1000. You can use mine to mock it up my rzr is on 40s and has a crappy custom suspension that breaks everything with bad angles
Get some 6" Super ATV portals and be done with it
@@BustedKnuckleVideo I have 6 inch portals and a gear reduction in the transmission
Trailing arm suspension systems sound pretty good, is there any reason I wouldn't want one on my daily driver?
Unnecessary for street use mostly
@@BustedKnuckleVideo I am building a rig that I want to use for everything. I want to be able to take it on long trips down the baja but also be able to drive and pull my 23 foot trailer too. I inherited my Dad's 1994 Dodge 2500 Cummins. I am ground up reworking the suspension 100% and want to be as capable as possible for the best all around. I am addicted to performance and off-roading stuff. I have been trying to figure out the best way to setup this rig to handle Baja type offroad as well as crawling. I really dig the ultra4 idea in making vehicles capable for anything you can throw at them. I know it's asking a lot out of a truck like this one but I am hoping to find a happy medium.
With the right shocks and deaver springs on the rear it can party pretty hard. We have a full size bronco with that setup and it gets after it.
I looked on the website but couldn't find this kit ? I'm interested in buying it but how long can I get the tube length ? How can I talk to you about what I want to use this kit for ? I'm building a 24 valve 2wd street racer and want the beef of these components because it will be pulling a trailer also
Trailing arms are for long travel off road applications not a 2wd street racer
@@BustedKnuckleVideo I know that sir but the strength of the components is what I'm after. How much is the kit and what part number do I have to use to get the kit you are showing sir ? I couldn't find a listing for the kit on the website .
Can I put trailing arm on my truck and still keep the rear bed frame?
most do a tube bed
ceramic balancing beads helps the "wobble-wobble" !
wobble is created from low tire pressure fluctuation, while spinning in mid-air
or going from heavy height/force to virtually 0 down force ! :] ]
ya need to spray your shite with PAM so the mud dont stick Jeffro !
That would be a lot of PAM! Anti wobble in this video is referring to the ability of the trailing arm to rotate and break the shock shaft
hi there what is the best anti squad number for my hilux on 40s now i have 82% and have chance to make it better should i? thanks in advance
This should help- th-cam.com/video/UzayUxQCWaY/w-d-xo.html
19:55 You vs the guys she tells you not to worry about XD......i had too
HA
Have you had any bad corrosion issues with the dissimilar metals?
nope
BustedKnuckleVideo nice
Changing the effective lever length on the shock. You can get away with less shock for travel but can't you tune out the difference by changing shock
Valving ? Change the amount of travel ? Adjust bumps?
Its all tunable
Hello I really like your videos is there any possible way you can send me the link for the 1 3/4 heim joint I would really appreciate it. Thanks 😊

I want to see that buggy with the new arm design in a race... The next weakest link will be the attachment points, you going to beef those up...?
they are already beef, Jake ran it on his Riot Buggy all last season with zero issues.
The trailing arms 1600.00. The singing free!!!! Im actually interested in putting a setup like this on a 2nd gen tacoma.
we actually just designed our own that are better for cheaper
@@BustedKnuckleVideo will they hold a 2nd gen tacoma?
If they are good enough for a rock bouncer they should have no problem under a Tacoma.
@@BustedKnuckleVideo do you have a link to the arms?
can we use trailing link suspension as front suspension?
that is called a leading arm and it can be done but is difficult to master
Lol we used to use too small of a wall and it would bend, but we fixed that so keep ordering! Sorry guys who purchased the old setup!
Only one set got bent so we beefed them up. 99% of people would never have an issue with the old ones.
From India
Bro tell about toyo tyres bj Baldwin car suspension work
Are these suspension is better than polaris
they work extremely well
How about upper trailing arms? Anyone insight on issues or benefits?
I guess they do the same thing with a shorter shock. It is all about packaging for us and this is the easiest way to package it all
You start running out of vertical height. The shocks attached to the lower arms are already close to the roof of the vehicle. Moving them up another 6-12 inches to the top bars would also move up the top of the shocks 6-12 inches.
What kind of welder are you using?
ESAB
Please, where i can buy this silent block? Have link?
silent block? You can buy trailing arm parts here- www.bustedknuckleoffroad.com
So are you welding steel to alum?
steel
I’d love to see a video series on building independent long travel front suspension
that might just happen
BustedKnuckleVideo well that just made my day!
PRO!
👊
awesome tech as usual. but why not just use a 1/2" wall tubing instead of costly aluminum links inside of steel tubing?
GREG LEBLOND
I am guessing to save weight
JSE Contractors Inc not really, you still have steel tubing, and then adding a thick piece of aluminum. On top of that your putting 2 different metals together that interact differently. And not to mention highly increasing the cost. You can get steal tubing in the $1.00 $1.25 per inch for 1/2" thick tubing.. but add $2.00-$2.50 per inch of aluminum, just added hundreds of dollars..
Unsprung weight and aluminum bounces back rather than bending
Smokin07ram aluminum is also more brittle and will split or crack while steel tubing I'll bend
Weight and strength are the main reasons
Man I done a lot of dirt track racing mods and street stock built all my cars from time I was 14 to now but I want to get into the rock crawling/bouncing I watch a lot of videos but learn more yours I just wanna build one drive it for about a year then probably sell it lol it’s just how I am but can you give any references to like some blue prints for a Chassis but I think my only problem will be the Suspension because it’s totally different from what I’m used to
We sell full chassis and chassis starter kits that way you get the suspension mounts already setup for you www.bustedknuckleoffroad.com
Will this work for a ford ranger prerunner
it can be made to work for sure
@@BustedKnuckleVideo ok thanks
Where is the whole kit on your website I don’t see it
bustedknuckleoffroad.com/Jake-Burkey-Riot-Buggy-Signature-Series-Trailing-Arm-Kit-1836.htm
Got a little squeeze in there
gotta keep it tight
Can these trailing arms go on my JK?
If you are custom building suspension for your JK then yes they can be made to work.
Actually its same size of CAT D6 front blade jack joints,
I think you can drill 5.5mm for grease pump joint And after each trail you can add 1mililiter of valvalin or hi viscous grease
why would you want to do that?
