Ian, it sure is nice to find you teaching what we know and not working in a scripted environment. Always loved your builds, and really learned a lot in the past, but the new show is another level entirely. THANK YOU
You obviously never watched Xtreme. He made me jealous of his skills & made me look bad every episode. Good times! 👍 Rock on Ian. Looking forward to seeing the new show under the new roof. Eh?
This is the first time Big Tire has ever popped up on my suggestions. I would have subscribed a long time ago. I am a welding instructor at a community college and I'm always trying to encourage my students to jump in on projects that intimidate them and show them that you don't need 50 grand worth of tools to make cool stuff. Anyway I've been contemplating putting airbags in my xj so I can run smaller "street tires" during my daily driving without it looking like a roller skate and hopefully some off-roading benefits as well. I'm looking forward to seeing the end results and how it performs. Thanks for the video Ian!!!
This video is pure gold 🤘 I plan on converting older vans. bought an 90's gmc k van pathfinder 4x4 to understand more and hopefully improve the suspension. then copy and paste it to my 89 roadtrek SUBSCRIBED!
I've been following you for quite a while now and this is the 1st big tire garage video I've seen. SO much info and detail just in this 1 video. That's my favorite part about it. Keep up the great work. Looking forward to seeing MANY more videos 👍🏼
Thanks Ian. Wow this one had a ton of info! I honestly thought it was close to being over at one point but was surprised to see I was just past the five minute mark.
Sucks, I can’t see this guy with out seeing Jessie. Both were such a massive staple of my childhood on weekends. Both of them contributed so much to my passion into cars/trucks. Also created so much of me and my fathers bonding on Saturday mornings.
We all still feel the loss of Jesse Combs but she lived and died doing what she loved, carry on brother that's what she would want us all to do in memory of her short time here!
Love the idea of the airbag suspension. Hopefully it works as well on the trail as it does in your head Ian. Will likely be a revolutionary change for rock crawling.
Glad to see ya doing so well since Extreme 4X4. Miss Jessy 😔🙏☝️… I fallow Gunpowder & Gasoline. Just saw S4 E8 the green Jeep. I also like how well you explain things. 🍻👍
Long time ago, there was an advertisement for a new series of Mechanic shows. 1 was Muscle car, I thought ya, I love those type of cars, 2 Horse Power. Who doesn't want to know more about building more horse power. 3-Trucks. Duh, I've had a truck all my life, sign me up. 4- Extreme 4X4. What ? naa. Not interested. Then I soon after these show's started I bought a '84 Jeep CJ-7. OMG I couldn't get enough of your show. Addicted. Even worse I just bought a '16 JK Rubicon. Ion, It's all YOUR fault. LOL !! I'm like allot of your fans, wish we could work an afternoon on a project with you. HMMM (Light Bulb )Get a sponsor to come up with something like that. 4 fans get to fly out to your place and turn wrenches with you for a day. Oh well, just a thought. Keep up the Great videos. When is your new shop going to be completed ?
New shop is about 90 percent done... we did some filming in part of it for Motortrend recently, and the next build for Big Tire Garage will be in the new space
Ian, Been following you since your first episode on 4x4 extreme. I have learned a lot from you. Keep up the good work. I too have a 900 sq ft shop and am slowly growing my arsenal of tools, etc...
@@BigTireGarage well it has been 2 years now you got the new shop for TV and YOU Tube do you still build stuff at your Garage Shop at Home off Tv AND THE INTERNET ??? that lift you were using on the build looks handy what kind of weight limits do they have ?? ,, my shop only has a 10 ft ceiling ,, I have a neck injury plus a lower back injury titanium in both locations ,, It gets hard to work on the ground under a auto ,, I have used a hoist it makes it nice ,, car ramps and jack stands are still a bit too low ,, keep up the Great Videos ,,
Bro, where you at? Haven't seen anything new from you on Amazon. I hope you're still working on this project. I was super stoked to see you fabricating again!
I also put dana 44s from jk on my comanche with an ls6, that domino effect it's so accurate you better plan everything because every change will affect the whole project. Love for the MANCHE
Will have to look at it again to remember it all. THANK YOU VERY MUCH! Used to own a Comanche. Great for living on a farm, but salty Québec roads (and an troubled separation) got the better of it. Can't wait for the next video.... And for the RamCharger! ;)
@@BigTireGarage GREAT! I suppose it'll be in your new shop, wich looks fantastic by the way! Love the metal framing. Will keep watching for the RamCharger and in the meantime, will enjoy all your videos as I've done since your "XTreme" time on TV. Take care, hey!
I've always wanted to do the air bags on a cantilever arm and rod, keep the bag up out of the danger zone and add suspension travel with the offset in the arm.
Never noticed he was gone from TV But did enjoy his shows Been reading alot about bump steer Every engineer ive herd talk about bump steer say you will always end up with some bump steer no matter what you do to correct it
A properly designed steering system will not have bump steer...fron the factort a car does not suffer from bump steer...so if you midify it correctly, it still won't have it.
Ian holy shit, good 2 see u bud!! Missed u on extreme 4x4,. Can't watch it it's not the same... I'm subbed,.. I've always imagined working with you. I'd love 2 apprentice,. Lmk if that's possible,. LoL Thanks 4 what u do for the 4x4 community
Hey lan I’ve ran into a somewhat difficult position on my 02 Tacoma build. I’ve installed a snorkel kit and started my rock sliders with my exo cage but cannot figure out how to run a tube along the passenger side a pillar due to the snorkel. Any advisor tips?? Thanks a lot for all your shows and videos I’ve built my Taco off a lot of knowledge I learned from you
Why have I not heard about this channel?!?!...dude...loved you on t.v....subbed as well...is this garage in Canada or?...if your in Canada I'd love to come and help with something...lol...anything really...
@big tire garage Do you have a follow up video for this one? I didn't see it and I really want to see how the airbags work out. Thanks and keep up the great work.
Touche..."the domino effect". I'm in the middle of my very first car project - ever. The goal: do an LS swap in a Jeep TJ. Simple right? (Stop chuckling.) Considering I didn't know what I didn't know, that simple decision has led to other major developments. Logistically, the original plan was to pull the 4.0, AX15, and NP231 and drop in the 5.3, 4l60e, and NP241C. That easy decision morphed into a complete body-off restoration, along with all the falling dominoes that I didn't even know to anticipate: Ford 8.8 rear-end swap Re-gear both axles Install front and rear lockers Sand-blast and POR15 the chassis (and axles) Re-build the wiring harness myself (Ugh!) Change out all of the gauges because the factory gauges do not work with the GM sensors Cut off the old and weld on new rear spring buckets Install all new suspension - bolt-on; I didn't know how to make my own. (By the way, how does one go about learning how to build his own suspension. Are you taking on mentees?) I learned to weld from starting this project. It's not complete. I am currently working on the Jeep's wiring harness - another unforeseen.
Have a JKU 6pac 3.5 MC GC and have been looking into incorperating Airrock in a DIY system with an integrated CVT onboard air. So looking forward to where this goes.
Interesting, I'm not convinced that building a full bump is a good idea; but whatever works for the builder is absolutely correct. The problem on the rear is visualizing instant center on the rear - which makes a huge difference on how well the truck hooks. On the front, you want the suspension to be at the center of the panhard bar's arc, otherwise, the vehicle will react differently depend on the direction you turn the wheel - the other issue is that the longest panhard bar you can install is actually more important for bump steer then being identical arcs (though usually you can get pretty close). Good luck in your new venture, Ian.
I like it good video a lot of us don't have very big shops I do my bills have a very small shop plus living off the grid really makes a challenge I'll be following your videos get getting ready to put the four link long-arm suspension in my 93 Grand Cherokee rear and a lot of us are going to the 8.8 Ford axle
I have been a long time follower. Glad to see your still on the air. Silly question what engine are you going to use? Shouldn't you mount that up before the 3 link so you know you have clearance?
What airbags did you use I've been looking to design an airbag system for my H3 Hummer so I can tow my trailer better. This design seems great because I also don't want to limit travel and would love for it to just drop away?
We actually bought our MJ's at the same time and I had hoped to get them done together, but I got too busy. Matt from @bleepinjeep is a blast to hang out with
@big tire garage I noticed that you don’t mention pinion angle at all. Can axles be set up in this manner at basically +\- zero degrees ‘full stuff’ and then worry about adjusting the final pinion angle after dropping the axle to ride height simply by adjusting the heims? I’m curious if this is how you would set pinion angle after using the way you’ve demonstrated starting at ‘full stuff’ in this video. I’m assuming at this point in a build you’d be more concerned with having the axle centered and square over anything.
Great video . Need advice. I have a 1963 k10 suburban w/ 292 and 3.73 gears . Would like to go all disc. What year of chevy should I look for to get a front axle? Thanks in advance for any help from all Gearheads
Nice , can you make a video on how to Set the geometry of the steering having problem with my, hoooo i forgot from how is the inner bracket that you are using for the upper arm in that 3 link. Thanks
When the axle drops away from the air bag, you'll have zero spring rate and the axle travel will have a dead spot with no tension pushing down on the axle. Then when you go from droop to compressed, there won't be any downforce during that period.
Yeah everyone says that, but that is a very common thing that happens in Coil Spring rigs with the axle drops away and the spring becomes unseated from the pocket
What kind of belly height are you shooting for ? (Ground to transfer/transmission crossmemeber) & for the unsprung weight issue on the bags shouldnt something like the antirock swaybar help out? But there shouldnt really be a problem being that my spring unseats from my tj most of the time when i fully flex out and disconnect my sway bar & i still get over any rock i want most of the time…….
It is getting sway bars....I want a belly height of about 20" at ride the wheelbase will work with that. As for unseating, everyone seems to worried about that, but when most jeep articulate you are right the spring has no pressure on the axle or comes unseated like you mentioned.
This is cool and all, great work and good filming, but this is no different then your former tv job. This is what makes TH-cam so great is that there aren’t deadlines and they don’t have to make it fit the cookie cutter “how to” show. Show us how you actually design one of these suspensions. You spent 3 mins on the rear suspension, and that was basically you just get it and weld it in. The real “shows” on TH-cam would have spent 5 days on the rear and gone through everything. I’m just saying take some time and really get into the details.
We are looking at doing some more specific "tech heavy" content....that focus on a specific part of the build....but we like the "feel" of this show so far
Hello i have a new idea this is going to be the first on its kind i just dont have resources to build at this time , it is going to be a mono hydraulic suspension system sound impossible but if you give this a shot , it will change of all suspension system as we all know tank you
Hey bud not sure if it's been asked before, but I was wondering what lift you're using. I need something to lift my K5 for axle swaps and what you're using seems perfect.
He mentions it all in the video of what he's using. But if you're interested in something like this (a 4 link and coilovers) that has already been designed for a Blazer, check out Off Road Design. They are in Colorado and they have a TON of stuff for straight axle Chevys. Good luck!
I have doubts about letting the axle end of the bag hang free. Air-springs are not forgiving to chafing, pinching, rubbing, and over-extension. You might want to look into some triple convoluted long-travel springs and make sure both ends are fixed. In a quick search I did, I found a triple convoluted spring with 10" of travel, 4" collapsed and 14" extended, it was $120.
10" of travel is not near enough...rubbing and chaffing really won't be an issue. I am more concerned about having a suspension component without any preload on it
@@eformance I am sure that you know that the spring and shock are not locating devices in a suspension system. The bag will land back in the poly locating "bucket" when the suspension compresses.
@@BigTireGarage I was thinking of what would happen when the suspension drooped away from the bag as well. I don't think having only unsprung weight on contact patch is the same as having a long travel coil over with some sprung weight transferred through the spring. Your axle will be able to articulate, but the traction is going to be proportional to the normal force on the contact patch which is only going to be the weight of one tire and wheel and half of the axle and I think half the links and shocks on that side if I remember correctly. Maybe with lockers it wouldn't matter, but I would think you'd have to use the lockers a lot more often than a suspension with a 14 or 16 inch travel coil over. Once the bags are pumped up, if you have five inches of up travel you are only going to have five inches of sprung down travel before the axle and bag separate. Anyway I enjoyed the video, but I would love to see a little more about the theory of suspension design maybe using one of the spreadsheet calculators on line. I think people are intimidated by them, but it's doesn't have to be overly complicated, and it would be good to hear from someone with experience about where to make trade offs.
@@Fix_It_Again_Tony yeah, that is my only concern to be honest, the suspension will be "unsprung" a lot sooner and there will not be any "preload" on it as well. But, I will be able to adjust weight transfer from the rear to the front by adjusting air pressure..it is by no means a coilover, but it is different.
@@BigTireGarage I assume those would not work for my stock TJ Dana 40 axle? I assume you got a JK axle from Dynatrac. I will still look into it though. Beefy is better!! Hahaa
Has anyone reverse engineered a rock crawler from measurements taken off the obstacles at Moab Utah? If so, is there video on the build? If you’re going to do this, let’s do this all the way from A-Z. :)
On the front axle, due to the track bar, at full stuff, wouldn't be centered under the frame. How do you account for push/pull of the track bar based on a static height to a full compression to a full extension?
I could spend an hour watching Ian teach us how to sharpen lawnmower blades. Thanks Ian!
Ian, it sure is nice to find you teaching what we know and not working in a scripted environment. Always loved your builds, and really learned a lot in the past, but the new show is another level entirely. THANK YOU

Rock on Ian. Looking forward to seeing the new show under the new roof. Eh?
@@Maxxis1941 I watched a ton of xtreme and it was still mind boggling how much ian could get done.

It is getting sway bars....I want a belly height of about 20" at ride the wheelbase will work with that. As for unseating, everyone seems to worried about that, but when most jeep articulate you are right the spring has no pressure on the axle or comes unseated like you mentioned.
What do you focus your dialogue at off-camera?
Different production style
What airbags are you running?
This is cool and all, great work and good filming, but this is no different then your former tv job. This is what makes TH-cam so great is that there aren’t deadlines and they don’t have to make it fit the cookie cutter “how to” show. Show us how you actually design one of these suspensions. You spent 3 mins on the rear suspension, and that was basically you just get it and weld it in. The real “shows” on TH-cam would have spent 5 days on the rear and gone through everything. I’m just saying take some time and really get into the details.
We are looking at doing some more specific "tech heavy" content....that focus on a specific part of the build....but we like the "feel" of this show so far
Hello i have a new idea this is going to be the first on its kind i just dont have resources to build at this time , it is going to be a mono hydraulic suspension system sound impossible but if you give this a shot , it will change of all suspension system as we all know tank you

Hey bud not sure if it's been asked before, but I was wondering what lift you're using. I need something to lift my K5 for axle swaps and what you're using seems perfect.
He mentions it all in the video of what he's using. But if you're interested in something like this (a 4 link and coilovers) that has already been designed for a Blazer, check out Off Road Design. They are in Colorado and they have a TON of stuff for straight axle Chevys. Good luck!
@@firefighteruppy9121 I'm actually talking about the vehicle lift, not the suspension lift. I didnt hear him mention the jack hes using.
@@Unknownkjn Oops... my bad. Yeah, that thing is pretty slick.
Isn't letting the axle droop away from the bag basically the same as big droop and an unloaded coil spring with a gap ?
Yep, my only conceen with this setup is the lack of preload in the system...but we will see if this works
I have doubts about letting the axle end of the bag hang free. Air-springs are not forgiving to chafing, pinching, rubbing, and over-extension. You might want to look into some triple convoluted long-travel springs and make sure both ends are fixed. In a quick search I did, I found a triple convoluted spring with 10" of travel, 4" collapsed and 14" extended, it was $120.
10" of travel is not near enough...rubbing and chaffing really won't be an issue. I am more concerned about having a suspension component without any preload on it
@@BigTireGarage How do you plan to guide the air-spring back into the pocket after it droops away?
@@eformance I am sure that you know that the spring and shock are not locating devices in a suspension system. The bag will land back in the poly locating "bucket" when the suspension compresses.
@@BigTireGarage
I was thinking of what would happen when the suspension drooped away from the bag as well. I don't think having only unsprung weight on contact patch is the same as having a long travel coil over with some sprung weight transferred through the spring. Your axle will be able to articulate, but the traction is going to be proportional to the normal force on the contact patch which is only going to be the weight of one tire and wheel and half of the axle and I think half the links and shocks on that side if I remember correctly. Maybe with lockers it wouldn't matter, but I would think you'd have to use the lockers a lot more often than a suspension with a 14 or 16 inch travel coil over. Once the bags are pumped up, if you have five inches of up travel you are only going to have five inches of sprung down travel before the axle and bag separate.
Anyway I enjoyed the video, but I would love to see a little more about the theory of suspension design maybe using one of the spreadsheet calculators on line. I think people are intimidated by them, but it's doesn't have to be overly complicated, and it would be good to hear from someone with experience about where to make trade offs.
@@Fix_It_Again_Tony yeah, that is my only concern to be honest, the suspension will be "unsprung" a lot sooner and there will not be any "preload" on it as well. But, I will be able to adjust weight transfer from the rear to the front by adjusting air pressure..it is by no means a coilover, but it is different.
What are those ball joints? I am looking for a new set for my TJ Dana 30 while I have the axle out installing an Artec truss.
They are from Dynatrac...heavy duty JK baljoints
@@BigTireGarage I assume those would not work for my stock TJ Dana 40 axle? I assume you got a JK axle from Dynatrac. I will still look into it though. Beefy is better!! Hahaa
Has anyone reverse engineered a rock crawler from measurements taken off the obstacles at Moab Utah? If so, is there video on the build? If you’re going to do this, let’s do this all the way from A-Z. :)
I'm glad you got rid of the "interviewer " camera angle. Just talk into the camera
Bag on bar is best
On the front axle, due to the track bar, at full stuff, wouldn't be centered under the frame. How do you account for push/pull of the track bar based on a static height to a full compression to a full extension?
You always build that portion of the suspension at ride height
Way cool!
