  1. Everything you need to do the job right! - Posted by: Big Red (3/30/15)

    I ordered this kit after considering many other kits both by Rough Country and others. I have to say that while this kit took some time to install the end results were fantastic. I did several other upgrades along the way, but I have to say that the control arms are second to none. This jeep with a total lift of almost 9 inches above stock between the suspension lift and the rubber size handles better than any factory Grand Cherokee that I have ever driven. I am a dedicated Rough Country Fanatic now and will only use Rough Country lifts in the Jeeps that I build.

  2. Quality!!! - Posted by: Rynomite (3/22/15)

    Great quality product for the price! The instructions need improvement! Even my friend who is a certified mechanic who helped me with the lift thinks so too. Install time says 4-6 hours. If you have a fully equip shop with a hydraulic lift then maybe... yet it took us 8 hours, in my friend drive way, just to do the front! So keep in mind if you are installing this lift kit on an older Jeep you may run into some minor problems so give yourself a couple days to complete the whole lift!... I would recommend ordering "Upper Front Control Arms", "Sway Bar Quick Disconnects" and " Longer Front Brake lines" to complete this kit! With saying all that I still recommend this lift kit!

  3. Great kit for the price - Posted by: jfflyboy (2/23/15)

    This kit was fantastic. I installed it with a friend in my driveway with minimal tools. You definitely need good mechanical knowledge to put it all on, but its not too tricky. The directions can be vague in some spots and they leave out a few steps. But if you are paying attention and use common sense it all goes together fine. I do recommend purchasing their adjustable track bar, sway bar quick disconnects, and adjustable upper control arms to really complete the kit. It will still be less expensive than other kits out there with the same features. In short, love the kit and my jeep looks great.
