Jeep® Performance Parts (JPP) 2 Lift Kit has been developed by Jeep® brand engineers and off-road enthusiasts and allows you to use larger tires. The kit includes 2.5" diameter aluminum body monotube FOX shock absorbers for cooler operation. The lift kit increases articulation and tire-to-ground contact and the longer front control arms optimize suspension tuning for on-road drivability while improving off-road capability. It works with electronic stability control although unique alignment specifications are required. The parts are easy to install as no driveshaft or brake line replacements are required. Rigorously tested for performance, durability, and corrosion, the parts in this kit are held to all FCA US LLC production standards.The kit comes in a reusable Jeep® branded wooden crate."
