Teraflex JL 4dr Lift Coil Springs are specifically engineered for diesel and 4xe Jeep Wrangler Unlimited models. Our engineers focused on extensive spring-rate tuning and dynamic balance between front and rear, as well as side-to-side load bias, to deliver exceptional highway handling and off-road performance.

Up front, progressive dual-rate lift coil springs provide consistent performance and predictable handling during normal street driving, similar to a linear-rate spring. As the axle begins to droop, the softer upper section of the coil spring unwinds to provide maximum articulation and improved spring retention.

These springs are tuned to accommodate the additional weight and unique load characteristics of diesel and 4xe models. For the best overall performance, we recommend pairing Teraflex Lift Coil Springs with Falcon Performance Shocks. Teraflex coil springs and Falcon shock absorbers are engineered together to optimize compression, rebound, ride quality, and vehicle stability both on and off road.
