Skyjacker JKU40FDR 4in Front Dual Rate Long Travel Coil Spring Set for 2007-2018 Jeep Wrangler JK Unlimited

Fits 2007-2018 Jeep Wrangler JK Unlimited 4-door models.

Skyjacker JKU40FDR Front Dual Rate Long Travel Coil Springs are engineered to provide a 4-inch lift while significantly increasing suspension travel and off-road capability. The dual-rate configuration delivers a comfortable, OEM-matched ride quality during daily driving while providing the necessary expansion to keep the spring securely seated in the bucket even at full suspension droop. This design maximizes articulation for technical off-roading without the risk of spring displacement.

Manufactured from a high-strength alloy, these springs are specifically designed to resist sagging and fatigue over time, outperforming standard replacement coils. Each spring is finished in a durable powder coating for superior corrosion resistance and longevity. These coils allow for larger tire fitment and improved ground clearance while maintaining the factory-intended ride characteristics.
