External marketplace context: This is the exact kit I put in my 01 Grand Cherokee. Easy install, and looks and drives awesome. Only complaint I have is because of the lack of rubber bushings in lower control arms you hear and feel every bump, no shock absorption in steel joints. On the plus side, they don’t sway or give out like rubber though. Be prepared though, It doesn’t drive like stock any more, use to drive like a car. To be expected in a lifted truck.All In all, I’d do it again.

External marketplace context: I've had a couple of different lifted vehicles including Ranco and Iron Rock. This is by far the worst. Its not really good for off roading, just a lifted look only. My Jeep WJ, sways tremendously with this kit on. Every time I go over a bump or turn the entire vehicle body sways around the frame like a bobble head toy. Don't plan on going over 60 mph on the freeway. Highway hazard. Shocks are lowest quality you can buy and went out after a year. 1 totally collapsed. Springs are not stiff at all and add to the swaying. I would steer away from this kit.

External marketplace context: I bought this lift directly from rough country and wish I would’ve spent the extra money at first for the Clayton long arm or something with bilstein shocks and different coils. The shocks dampened but didn’t allow for a smoother ride, the coils were very stiff and rusted and sagged within a year from mild off-roading, a shock exploded through the seal from some lighter off-roading, all the shocks started to rust within a year, the lower control arm ball joints wore and got play in them and began knocking over bumps despite being greased every month, the powder coat started rusting within a year, and the poly bushings started tearing and getting holes in them after a year. Some of the good things this lift has to offer is it gets you lifted fast and cheap and the swap bar disconnects are well made and held up to this day. I would definitely recommend another lift for the long run because you would end up spending more time and money in the long run maintaining a lift that performs worse than stock.

External marketplace context: Your kit will sag and lose its height in a few months to 1 year. Spend a little more and get a good kit from IRO
