07-18 JK 4Dr 3.5 Coil Box Kit

Increase clearance, performance, and ride quality with JKS JSPEC™ 3.5 Inch lift dual rate coil springs. This kit includes a complete set of matching front and rear coil springs for a level 3.5 Inch lift. The dual rate springs provide a smooth and comfortable ride on-road and transition to a firmer rate when tire movement increases off-road for enhanced vehicle control. Another benefit is the longer overall length, which allows for the use of longer shocks for increased wheel travel. JSPEC™ coils deliver the desired ride and performance, whether you're loaded with gear for an expedition, running light for rock-crawling, or traveling with friends to the beach.
