Everything seamed to be of great quality. I do wish that it had come with new bolts for the leaf spring as I had to cut mine out and go buy new, opted to buy Bilstein shocks instead of RE shocks.

This was just a pain and not finished yet. Put in on my only good day off - Sunday. Sent me the wrong u-bolts. Apparently I have the heavy duty rear axle Dana 44 so the old ones were too short and the new ones were 1/4 inch not wide enough. Actually ends up taking all week to do. 8 hrs my butt! Still have horrible driveline vibration. Now need to put in slip yoke elim kit & c/v driveshaft (another $800!!!) Will be pretty sweet when done but what a pain it's been!
This kit was easy enough to install. As typical my rusty jeep was a royal pain to get the old parts off. The new kit fit well and looks fantastic. A small rake to the front puts your XJ in a perfect stance. I opted for Bilstein 5100's to top this off and it rides great! I'd only say that i think that this kit could be a little more complete by simply Including new leaf spring bolts & Control Arm Bolts. I'd also like to see a pair of Axel Shims included. All of these pieces would make this kit just that much better. The addition of these pieces would be cheap and not require to run around locating them. Installed this kit with a transfercase drop and 2 degree shims and i've not no driveline vibes. Runs and rides great!
When I go 4wheeling I don't like getting hung up on obstacles and the 3.5 lift gives me the height I'm looking for without the added cost of a 4" lift. It performs well on the road in fact I think the ride is better. However, it is difficult for my wife and kids to get in with it being so high. I will have to get a step bar for them. I didn't install the product so I can't comment on the installation. But my 2012 Wrangler Unlimited Rubicon looks and drives great.

Asked by alvaro prieto from mexico on
Hello Alvaro, With the Rubicon Express 4.5 Inch Superflex Lift Kit you will need the exhaust spacer for this setup. If you don't run the spacer your front drive shaft will hit the exhaust. If you have anymore questions feel free to ask, Thank you.
