Simply the
BEST ZJ lift kit available anywhere now available up to 4.5" of lift! Excellent ride quality on the road, and incredible off road performance. Our kit rides so well, you might even forget you're driving a lifted vehicle. More suspension articulation equates to more traction even without locking differentials and this kit delivers the flex you need.
Performance and durability are both key factors in the design of this suspension system. You won't have to ever worry about bending these control arms because they are made from 2" x 5/16" wall DOM tubing with a
LIFETIME WARRANTY! All mounting bracketry is precision laser cut from 1/4" and 3/16" steel plate. You will not believe the performance gains for yourself until you get on your favorite trail where you didn't have the traction available to get through.
Take your family and friends with you without the embarrassingly rough ride of many tall lift kits out there. Your highway ride will be a dream come true with this kit. The long front and rear control arms keep the suspension geometry much closer to stock for an impressively smooth ride at 4.5 inches of lift. Add an Addco rear sway bar and the WJ will ride BETTER than stock!!
We use an exclusive, non-binding, 3 link setup up front that has a trio of front long arms, and a 4 link rear that will flex more than you thought possible. The bushings at the unibody are greasable and pivot to allow as much suspension travel as the shocks of your choice will allow. Tons of adjustment is built in to each link for you to be able to dial your suspension perfectly to your application.

NOTES:
This suspension lift kit requires a front double cardan driveshaft. This kit may require a longer front and/or longer rear driveshaft to eliminate driveshaft vibration and maintain adequate slip engagement. Due to the tall lift height of this suspension kit your OEM driveshafts might not be long enough. Driveshaft length depends on many factors such as the engine, transfer case, and rear axle that your Jeep is equipped with as well as tire size and your desired wheel base. Some ZJ OEM driveshafts will work with this kit if the wheel base isn’t stretched too far. Ensure your rear driveshaft has adequate engagement in the transfer case by marking the slip yoke then remove the drive shaft and measure the amount of engagement. Minimum 50% of slip length should be engaged in transfer case. To help eliminate drivetrain vibration, it is recommended that the engine and transmission mounts be replaced if they are worn or if they are allowing the engine and transmission to sag. Excessive movement in worn engine and transmission mounts has been known to cause vibration under acceleration with tall lift kits.Contact Iron Rock Off Road with any questions before, during, or after installation.1-877-919-JEEP1-952-210-7185This kit has not been tested with aftermarket headers and is known not to work with Doug Thorley Headers without modification.
