Well on my 99 XJ I was running a Rusty's 4.5" lift and had no complaints, but when that rig was totalled I decided to go with the Rough Country Lift instead. For the most part I think the Rough Country variant is a better buy, my only complaint would be the lack of an adjustable trac-bar. For about the same price the Rusty's kit does include that. Otherwise however I liked this kit a lot. It was easier to install and the fact that the shock bushings were already installed was a really nice touch. I've installed a lot of lift and lowering kits on different vehicles for friends and myself and this was the first time I'd ever had the shocks show up with bushings already installed. Its a small touch, but sometimes the small details are the important ones. I also really liked how the kit came with both sizes of U-bolts for either the D35 or 8.25 rear axles. It saved me a lot of headache as my 92 came with a D35, but about a week or two after installing the lift I was able to acquire and install an 8.25. I have no complaints about the ride with the RC shocks and this thing definately flexes. First time on the trail I had to trim out my fenders because my 32's crashed into them and got wedged. Oh yeah, one more really nice little dtail was that my shims were already installed on my leafsprings. Again, its a small detail but just made the whole installation process that much nicer.
Here is a nice flex shot, notice how both rear tires are still flat and the chassis itself is barely leaning.
Here are the only things I would recommend:
1) In the part of the instructions that say you can fit 32x11.5 tires w/o trimming, you should add that bump stops are required. I'm on the rim offset you guys recommended and learned real quick that my fenders needed trimming.
2) If you can add in an adjustable trac-bar with the kit w/o making a huge price increase, that would make this kit just about perfect.
3) Keep up the good work, because I never expected a 650$ lift kit to perform this damn well. Especially as I'm not running drop brackets and still have my OEM upper control arms.
note: I am running new leafpacksas opposed to AAL's, quite frankly I wouldn't use AAL ever as they are crap. It wasn't that much more for the new spring packs from RC and its worth the lack of headache.
Once again, RC is defiantely a great bang for the buck and if I wasn't going LA I'd continue to run all their stuff on my suspension. That being said, I'll be running RC shocks and springs with my TnT Y-Link setup.
