Dedicated overland travel requires unique spring rates to handle heavy loads and continuous mechanical resonance compared to standard coil spring rates. That’s why we paid special attention during spring rate tuning and development of our Outback Lift Coil Springs. All this adds up to our load-enhanced heavy-rate lift coil springs that meet the demands of a fully loaded Jeep while maintaining advertised lift height. TeraFlex JL: Lift Coil Springs are perfectly engineered for your JL Jeep Wrangler/Unlimited. 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. Around back, we chose the same tried and true linear rate technology preferred by most automakers including Jeep. Linear rate springs provide the maximum number of active coils under load for consistent performance and predictable handling throughout the full range of suspension travel both on- and off-road. Rear Lift Coil Springs are corner specific. We recommend pairing TeraFlex Lift Coil Springs with Falcon Performance Shocks for superior performance. TeraFlex Lift Coil Springs and Falcon Performance Shocks have been engineered together to improve both compression and rebound for optimal vehicle stability.
These application-specific load-enhanced heavy-rate lift coil springs will provide a firmer ride with an empty payload.
Advertised lift heights are not actual final lift height. Use the coil spring lift height descriptions as the average lift height that may be achieved between the front and rear of the vehicle. Other variables will affect the actual final lift height such as a winch, aftermarket bumpers, full-size spare tire, loaded cargo weight, etc.
