Teraflex JL 4dr: 2.5” Lift Outback Coil Spring Pair – Front

Overland travel demands specialized spring rates to handle heavy loads and continuous mechanical stress, which differ from standard coil spring rates. That's why we focused on precise spring rate tuning during the development of our Outback Lift Coil Springs. These heavy-rate, load-enhanced lift coil springs are designed to meet the needs of a fully loaded Jeep while maintaining the advertised lift height. 

TeraFlex JL: Lift Coil Springs are meticulously engineered for your JL Jeep Wrangler/Unlimited. Our engineers concentrated on extensive rate tuning and achieving a dynamic balance between front, rear, and side-to-side load distribution, resulting in Lift Coil Springs that provide exceptional highway handling and off-road performance. 

For the front, we selected progressive dual-rate lift coil springs, offering optimal performance both on and off-road. These dual-rate coil springs deliver consistent performance and predictable handling during normal street driving, similar to a linear rate spring. As the axle droops, the softer upper section of the coil spring unwinds, allowing for maximum flex and spring retention.

For superior performance, we recommend pairing TeraFlex Lift Coil Springs with Falcon Performance Shocks. These components have been engineered together to enhance both compression and rebound, ensuring optimal vehicle stability.

Product Note: 

• These application-specific, load-enhanced heavy-rate lift coil springs provide a firmer ride when the vehicle has an empty payload.
• 3.0L EcoDiesel V-6 models require the 1” Front Coil Spring Spacer Adjustment Kit (# 1155100) to properly level the vehicle — this is not included.
• The advertised lift heights represent average lift measurements that may be achieved between the front and rear of the vehicle. Actual final lift height can vary due to factors like a winch, aftermarket bumpers, full-size spare tire, loaded cargo weight, and other variables.
