Synergy MFG Jeep JL Multi-Rate Front Lift Coil Springs. Synergy MFG has designed these springs from a clean sheet for the new Wrangler platform. All springs are multi-rate and have been designed to make a great platform even better.These springs are unique to the JL and not shared with the JK or other vehicles. Like OEM, Synergy coil springs are unique lengths to account for load differences on each corner of the vehicle. There are right and left specific springs front and rear to guarantee the vehicle will sit level.Springs are designed to be used with up to .75 inch of front spring spacer without requiring additional bump stop spacing. Multi-rate design has a softer initial rate which prevents the spring from coming loose in the coil tower, even with long travel shocks. The ride rate is slightly stiffer than the OEM springs to account for additional weight from bumpers, winches, skid plates and gear.Springs are proudly manufactured in the United States of the highest quality steel. Springs are designed to be able to set solid (fully collapse) without overstressing the material and are pre-set from the factory meaning the springs will never sag or set.Benefits:Increased ride qualityIncreased wheel travel/articulation/tractionNo spring bowingLifetime warranty/guarantee against sagging and breakage
