The Skyjacker JL40RBLTD suspension lift kit is specifically engineered for Jeep Wrangler JL Rubicon Diesel 4-door models, delivering 3.5 to 4 inches of lift height. This comprehensive component box system is designed to enhance off-road capability while maintaining on-road comfort and factory Electronic Stability Control (ESC) functionality.

Progressive Variable Rate Coil Springs:

Skyjacker's innovative 2-stage dual rate long travel coil springs feature a unique progressive spring rate design. The 1st Flex Rate stage provides a comfortable ride quality with enhanced articulation capability, expanding during full suspension droop to keep coil springs properly seated and maintain tire contact with terrain. The 2nd Ride Rate stage engages only after compression past the flex rate, delivering coordinated support that works with the Wrangler's distinctive handling characteristics. Rear coils are engineered side-specific for optimal performance.

• Front adjustable track bar with pressed-in heavy-duty OEM-style rubber bushing, adjustable 3/4-inch heavy-duty rod end, jam nut, and alignment bushings
• Heavy-duty rear track bar upper mount bracket for proper axle centering
• Front and rear bump stop spacers that bolt to axle bump pads for controlled suspension travel
• Front and rear extended-length sway bar end links with pressed-in HD OEM-style rubber bushings for full articulation capability

This lift system maintains proper suspension geometry to ensure the Electronic Stability Control system functions within factory parameters, providing confident handling both on and off the trail.
