Skyjacker Suspension JL40BKXLT 4 Inch Suspension Lift Kit with Remote Reservoir Shocks

The Skyjacker JL40BKXLT 4-Inch Suspension Lift System delivers comprehensive lifting capability engineered specifically for the Jeep Wrangler JL. This complete kit transforms your vehicle's off-road performance with advanced suspension technology and precision-engineered components.

Progressive Dual-Rate Coil Springs:

At the heart of this system are Skyjacker's specially engineered 2-stage dual rate long travel coils. The progressive spring design features a flexible first stage that delivers comfortable on-road ride quality while maintaining articulation capability during off-road travel. As the suspension extends to full droop, this flex rate keeps coil springs properly seated and maintains tire contact with terrain. The second ride rate stage engages during compression, providing controlled support under load. Rear coils are side-specific to coordinate with the Wrangler's unique suspension geometry.

ADX 2.0 Adventure Series Remote Reservoir Shocks:

This kit includes Skyjacker's ADX 2.0 aluminum monotube shocks with external remote reservoirs. These race-inspired dampers feature full-displaced valving technology optimized for high-speed desert running while maintaining excellent low-speed crawling performance. The external reservoir separates pressurized nitrogen gas from hydraulic oil using an Internal Floating Piston (IFP), preventing cavitation and fade during demanding off-road use.

Complete Hardware Package Includes:

• Adjustable front track bar with heavy-duty 3/4-inch rod end, jam nut, and HD OEM-style rubber bushings pre-installed
• Heavy-duty rear track bar upper mount bracket for proper axle centering
• Front and rear bump stop spacers that bolt to axle pads to control suspension travel
• Extended-length front and rear sway bar end links with pre-installed HD rubber bushings for full articulation capability

This comprehensive system provides everything needed for a professional 4-inch lift installation, combining improved ground clearance with maintained ride quality and enhanced off-road capability.
