Skyjacker Suspension JL40BKXLTD 4 Inch Lift Kit with Remote Reservoir Shocks for Jeep Wrangler JL

The Skyjacker JL40BKXLTD 4-inch suspension lift system delivers a complete solution for transforming your Jeep Wrangler JL's off-road capability and stance. This comprehensive kit combines advanced coil spring technology with premium remote reservoir shocks to provide exceptional performance both on the trail and on the highway.

Progressive Dual-Rate Coil Springs:

Skyjacker engineered these long-travel coils with a unique 2-stage progressive design. The first flex rate stage provides a comfortable street ride while allowing increased articulation during compression. As the suspension drops to full droop, the flex rate expands to keep coils properly seated and tires planted on terrain. The second ride rate stage engages only after compression past the flex rate, delivering controlled support under load. Rear coils are side-specific to work with the Wrangler's unique suspension geometry.

ADX 2.0 Adventure Series Remote Reservoir Shocks:

These aluminum monotube shocks feature race-inspired full-displaced valving designed for high-speed desert running while maintaining excellent low-speed crawl performance. The external remote reservoir separates pressurized nitrogen gas from shock oil using an Internal Floating Piston (IFP), preventing cavitation and fade during extreme use.

Complete Kit Includes:

• Progressive dual-rate front and rear coil springs with side-specific rear coils
• Four ADX 2.0 remote reservoir aluminum monotube shocks
• Adjustable front track bar with HD OEM-style rubber bushings and 3/4-inch heavy-duty rod end
• Heavy-duty rear track bar upper mount bracket for proper axle centering
• Front and rear bump stop spacers to maintain safe suspension travel limits
• Extended-length front and rear sway bar end links with pressed-in HD bushings for full articulation

This bolt-on system provides the ground clearance needed for larger tires while maintaining excellent ride quality and handling characteristics on and off the pavement.
