Pros: Great workmanship, great lift. Makes the TJ stand like it's supposed to. Offroad capability with great a great daily driving ride.
Comments: This kit is great for those who drive their Jeep every day and take it on the trail on the weekends. It will not let you down! I'm running 33's on 17 inch rims.
Pros: Solid build quality with solid steel components.
Cons: I just am getting it put on but it might be a little difficult to get it all adjusted just right.
Comments: Build quality seems very good, and the parts are solid. I'm just getting it installed so we'll see how much work it takes to get them adjusted.
Pros: Great Ride, flexes like crazy, super beefy control arms.
Comments: You cant go wrong with the abuse proof warranty!

Pros: Man size lift!
Cons: install could have been easier.
Comments: This is indeed a man size lift. I have the PRO version and so its aluminium makes the kit lighter but just as stout. I bought the RRD remote shocks to go with it so now my jeep feels like it could crawl over anything. I got way more that 3.5 inches of lift. I would estimate 4.5 to 5 inches of lift and that is with heavy aftermarket steel bumpers, tire carriers, and a winch.
All in all its a great kit that moves well. I do get a little more body roll than before but considering the amount of lift I figured that just happens. It is pricey and you may need to get creative with some of the installation but you wont regret it. Kit did not have anything for steering stabilizers so that is an additional piece that you will need to add in addition to this kit.

Noisy rod ends
No Zerk fittings
Comments: This setup has TONS of flex. I never have to worry about busting up the control arms on a rock as they are made of solid stock steel.
However, the rod ends/joints are manufactured so tightly that Rock Krawler reccomends using 2-in-1 oil by means of a allen screw @ ea. link end-- regular grease gun lube by ways of zerk fitting is not possible. For that reason, routine maintenance is a royal pain as some screw fittings are not accessible w/ an oil/lube can.
Rod ends are also both RIGHT HAND threaded so any adjustment requires complete removal.
I would recommend this product for its stoutness & performance, yet not for the aforementioned nuances above. You decide what your priorities are . . .
