The front linear rate Carli springs will lift your Jeep JKU 2.5” while the rear is lifted 3.0” utilizing progressive coil springs.
When lifting the front end of a straight axle vehicle, the front axle is pulled off-center unless the proper linkages are addressed. This system includes an Adjustable Track Bar that’s designed to extend – we provide this measurement – to correct the driver’s side axle shift. Included in the system, we provide extended sway bar end links with spherical bearings to accommodate the extended travel and maintain the factory Rubicon Sway Bar Disconnect. The last piece of the puzzle; extended stainless brake lines ensure the bottom of the new travel stroke can be reached without ancillary component stress. A short billet bump riser is included to match the front shock travel.
To match the front and provide a bit of rake, the rear is lifted 3” with a multi-rate coil spring ensuring a supple ride and reasonable carry capacity. The rear geometry being similar to the front, everything is included to support flawless operation of all components. A rear Track Bar Riser and adjustable track bar correct the axle position and minimize yaw (side to side movement of the body as the axle travels), Extended Sway Bar Links are included to accommodate the extended travel stroke as are Stainless Brake Lines and Brake Line Routing Bracket guiding the longer brake lines clear of all moving components. Fabricated rear bump risers.
