Skyjacker Suspension JL40RBKXLT 4 Inch Suspension Lift Kit with Remote Reservoir Shocks

The Skyjacker JL40RBKXLT 4-inch suspension lift system delivers premium off-road performance through advanced engineering and race-inspired components designed specifically for the Jeep Wrangler JL.

Progressive Dual-Rate Coil Springs:

At the heart of this system are Skyjacker's engineered 2-stage dual rate long travel coil springs. These progressive coils feature a flexible first stage that delivers comfortable on-road ride quality while allowing maximum articulation during off-road crawling. As the suspension extends to full droop, the flex rate keeps coils seated in the upper mount and maintains tire contact with terrain. The second ride rate stage engages under compression, providing the support needed for higher-speed off-road driving. Rear coils are side-specific to coordinate with the Wrangler's unique suspension geometry.

ADX 2.0 Adventure Series Remote Reservoir Shocks:

Included ADX 2.0 aluminum monotube shocks feature external remote reservoirs with Internal Floating Piston (IFP) technology that separates pressurized nitrogen gas from oil, preventing cavitation and fade during demanding off-road use. The full-displaced valving system is engineered for high-speed desert running while maintaining exceptional control at crawling speeds.

Complete System Includes:

• Progressive dual-rate long travel coil springs (side-specific rear coils)
• ADX 2.0 remote reservoir aluminum monotube shocks
• Adjustable front track bar with HD OEM-style rubber bushing 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 control suspension travel
• Extended-length front and rear sway bar end links with HD OEM-style rubber bushings

This comprehensive lift system provides the increased ground clearance, suspension travel, and component durability needed for serious off-road adventures while maintaining street-friendly ride quality.
