Jeep Wrangler Suspension Lift Kit - Rear - Skyjacker - Dual Rate Long Travel Coil Springs - 4in Lift - `21-`24

Jeep Wrangler Suspension Lift Kit - Rear - Skyjacker - Dual Rate Long Travel Coil Springs - 4in Lift - 21-24. This rear coil spring kit from Skyjacker is a direct-fit upgrade designed to add 4 inches of lift to compatible Jeep Wrangler JL Non-Rubicon models while improving articulation and ride control.

Skyjacker engineered these progressive 2-stage dual rate long travel coils to balance daily comfort with off-road capability. The first Flex Rate stage provides compliant suspension travel and increased articulation so the tires stay in contact with rough terrain and the coils remain seated in the upper mount during full droop. After compression past the flex stage, the 2nd Ride Rate engages to control body movement and maintain handling characteristics. These rear coils are side-specific and designed to work with the factory Electronic Stability Control (ESC) system. Installation is straightforward: straight bolt-on, direct fit, simple remove-and-replace, and engineered to preserve OEM suspension geometry.
