Details

Increase clearance, performance and ride quality with a set of JKS JSPEC™ 3.5" lift dual rate coil springs. Fits 2007-2018 Jeep Wrangler JK 4 Door. Includes a complete set of matching front and rear coil springs for a level 3.5" lift. Dual rate springs provide smooth comfortable ride on road, and transition to a firmer rate when tire movement increases off-road for increased vehicle control. Another benefit is the longer overall length, which allows the use of longer shocks for more wheel travel. Whether loaded down with gear for a weeklong expedition, running light for some rock-crawling fun or loaded with a few friends for a trip to the beach, JSPEC™ coils provide the ride you want and the performance you need.
