The JKS JSPEC 3.5" dual-rate coil spring kit fits 2007–2018 Jeep Wrangler JK 4-door models and provides a level 3.5" lift. Matched front and rear springs deliver a compliant on-road ride that shifts to firmer control as suspension travel increases off-road. The longer overall spring length accommodates longer shocks for greater wheel travel when the vehicle is loaded or used in demanding terrain.
