​Superlift’s 4 Inch Lift Long Arm System for the 2007-2017 Jeep Wrangler Unlimited is intentionally over-built to be the best. Our uniquely engineered design adds strength and durability and has bonus features that others kits do not offer.

This kit features Superlift’s ROCK RUNNER On-Vehicle Adjustable control arms. The on-vehicle adjustment eliminates the hassle of removing and adjusting your control arms and track bars multiple times to get the axles aligned. Simply loosen the pinch bolts and adjust the “double adjustment” sleeve as needed. This set up will allow you to fine tune the axle versus “get it close”.

The ROCK RUNNER Control arms constructed with heavy wall DOM tubing and feature dual durometer bushings at the axle mounts and flex joints with Nylatron races at the frame.

This Long Arm kit is available with Superlift, Bilstein 5100, Fox 2.0, or Fox 2.0 Reservoir shock absorbers. You can also choose the no shock option to run a shock of your choosing.
