I did the opposite on my old cherokee, I did 6" of lift and 31s. Looked badass and never tore anything up on the the fender or in the wheel well.


I don't feel like working on anything at this time so i sold my yj.

I run 33's on 1.5" and DD my Jeep. Very drive able this way. And pretty capable off-road. People will always hate on other setups. I would love to see where this goes though. There is definitely potential.

2000 Red XJ w/ 350k+, AW4, NP231, Locked Rear, HD Crown Leafs, trimmed to fit 33's, soon to be a donor
2000 Silver XJ, Drivetrain from the Red XJ, Stiffened, IRO leafs, RE coils, custom 3 link, WJ knuckles, 35's <=== In the works

I've been kicking around the idea of doing this with mine for a couple years now. 3.5" RE Superflex kit, trimmed fenders, Bushwackers, 33's. I'm definitely going to keep an eye on this cause I now have a garage that I'll be able to work in. IMO, if people don't understand the benefit of doing this, ignore them. Good luck.

Alright so now I'm in the process of ordering longer shocks, should I wait till I get the long arms installed and disconnect the shocks and measure how much travel I have? Cause I don't mind the coil dropping a good few inches but also don't want it falling out either lol

If it were me I would wait and measure. Unless you really like spending money twice there's no reason not to wait and me sure. Since you are doing something that isn't well documented I don't think there's much you can go off of.

I ran T&T Customs y-link long arms on my XJ when it was sitting at 4" true lift height, turning 35s. The only thing that speaks against long- arming using the available bolt-on kits in general is one simple thing: radius arm long arms don't behave as well as a true 3-link or 4-link.That being said, radius arm long arms beat the hell out of short arm lift at as low as 3" lift height - unless you modify LCA and UCA brackets on the axle.


My solution on the ZJ was that I raised the LCA and UCA mounts on the axles by 3" (at the same time moved them back accordingly), thus maintaining original 4- link geometry using DIY adjustable short arms built with Metalcloak duroflex joints. The result? Amazing. Ride quality is the same as stock - if not better - and I can go through head- sized boulder sections on the trails @ 20-30mph Compared to the brackets being at their original location and CAs at an angle, the difference is huge. Considering I'm using the same shocks, the difference came from just the angle of the CAs.


People saying it's pointless to long-arm (or modify CA brackets) @ 3" or even up at 4.5" of lift: sorry, but you don't have a clue.
When you lift a XJ, ZJ or TJ, things get messy very quickly. You can't fight physics/ geometry, and at as low as 3" of lift height the front axle suspension geometry is already messed up pretty badly. It goes even worse from there on. If you were to check what happens to the 4-link geometry at 3" or 4" of lift height, you'd be surprised.

Yeah that's what I figured, I'm looking at either rustys 200 series monotubes or 5100s, I don't mind limiting up travel because I'll have to anyways for 33s

Will do, I'm the same, I don't wanna go any higher bc I've already had some moments on the trails that if I would have been a tad more top heavy I would have been on my side
