The 2.5-inch Lift Kit for 2018 Wrangler JL Unlimited is a complete suspension system that is designed specifically for the new Wrangler JL. The basis of the kit are new coil springs that are location-specific with spring rates calculated to deliver a level stance while providing additional clearance for larger tires. The kit also features four (4) Fox 2.0 IFP nitrogen-charged shocks capable of smoothing out the roughest of terrain. All new extended-length sway bar end links and compression-stop spacers keep the suspension travel safely in check for reliable off-road performance. All installation hardware is included for an easy installation and with the added protection of our 5-Year Limited Warranty.
