TeraFlex JT: Lift Rear Coil Springs are perfectly engineered for your JT Jeep Gladiator. Our engineers focused on extensive rate tuning and dynamic balance between front and rear and side-to-side load bias to produce Lift Coil Springs that deliver unsurpassed highway handling and off-road performance. Out back, we chose progressive triple-rate lift coil springs that provide optimal performance both on and off road as well as while towing. These progressive triple-rate coil springs provide consistent performance and predictable handling throughout normal street driving - just like a linear rate spring. When the axle begins to droop, the softer sprung upper section of the coil spring begins to unwind for maximum flex and spring retention. The stiffer sprung lower section of the coil provides stability while towing. Additionally, we lowered the towing coils to improve ride quality while unladen. We recommend pairing TeraFlex Lift Coil Springs with Falcon Performance Shocks for superior performance. TeraFlex coil springs and Falcon shock absorbers have been engineered together to improve both compression and rebound for optimal vehicle stability.
