Whether you have a Jeep JK, TJ, LJ, YJ, CJ, ZJ Grand Cherokee or XJ Cherokee at Rubicon Express we are enthusiast who understand that everyone wants to customize their rig a little bit differently. With lift height options from 3.5 to 5.5 inches, options of Mono-Tube or Twin-Tube shocks, and systems including long arm kits, coil over conversions, progressive spring, and Extreme-Duty leaf spring options, Rubicon Express has an extreme-duty kit that is right for your specific needs. Installing a slip yoke elminator and CV driveshaft is required when using a long arm system. Exhaust modification may be required
Fairly complete kit with everything you need. I took the bottom/smallest leaf out of the rear springs in consideration of my light, topless Jeep.
I ordered this through another company since 4WP was out of stock and they left several parts out of the kit. I contacted Rubicon Express and received a response within the day and they immediately sent out the missing pieces, no questions asked. Any technical questions were answered immediately. Lift is great quality, just a bear to install as with all long arm kits. Would definitely recommend.
Very happy with the customer service at the Tigard store Sam, Austin and Tom are always very helpful when I stop in to pick up my orders and always ready to answer any additional questions I have. As an ASE Master Tech The in-store pick up with the free shipping it is much appreciated. Thank you respectfully
The lift is awesome! I will recommend it to everyone. I will not recommend that you buy it from 4wheel parts. It’s Sad such a great product is sold at a horrible store.

Q: Can this lift kit be installed after frame stiffeners are installed on a Jeep XJ? Answer this question
A: Stiffeners would make it very difficult to install. I installed my steffiners after I installed the center section and cut my stiffeners to butt up against the rubicon express center section crossmember
