Let me start by saying this is a great forum...unfortunately my wj spun a rod bearing.so my lift money has been redirected to new engine rebuild.But this moment of pause may be a good thing...I had decided on the 4in rough country lift...but the more threads I read I'm thinking that might be a bad idea....its a daily driver that sees light off roading...but since my expedition got totaled my wj is doing double duty as tow rig...I've never lifted a coil on solid axle so I'm unsure of the pitfalls...I've had ifs 2500 GMC with 8 inch lift that towed without any issues...and a few square body chevys and full size Broncos...I've had 3 xjs but never felt the need to lift them...would a bb lift be more what I need? Or go 4in but only mess with the long arm kit? The Rubiconexpress or Rc bb lift better?
Bb's are pretty much the same. And since they run 80$ or so its a good place to start and decide if you want to go bigger or not. They can usually be resold fairly easily. Jgcparts.com is my recommendation .
That's most likely where I will start. I don't see a lot of off-road and I am somewhat disabled, so it's best for me, for now. I do want to run the life out of my Michelins before I do it, though. I saw some Michelins in the correct size for the 2" BB, but they sure are expensive. I'm a firm believer in "you get what you pay for."
There are a lot of people that will bag on the RC kit but it's not that bad. I've got the RC X-Series kit (4") and I think I'm doing fine. Still balancing out some of the bumpsteer (or slight DW whatever you call it) but otherwise it's ok. The ride's not "like a Cadillac" but I expected that.. I would've bought a Caddy if I wanted to ride down the road that way.
Even though most manufacturers don't warn you about it, DW can happen easily on any kit (including a LA kit) and it's typically caused by worn suspension parts. You'll want to factor in also replacing all TRE's, Axle Bushings, Ball Joints, maybe hubs and a few other odds and ends too. For me, it was a good choice. Is it top of the line, no. Do I need top of the line? No.
With any kit I'd recommend getting a WD hitch if you're planning on towing with it. That'll help level out your ride (and the trailer) and make it easier on everything (rear end, suspension, transmission, etc).
