Skyjacker Suspension JL25RBLT 2.5" Component Box Lift Kit for Jeep Wrangler JL 4-Door Rubicon

The Skyjacker JL25RBLT 2.5-inch Component Box delivers a complete suspension upgrade engineered specifically for the Jeep Wrangler JL 4-door Rubicon. This comprehensive kit features Skyjacker's innovative progressive variable rate coil springs designed to optimize both on-road comfort and off-road performance.

Progressive Dual-Rate Coil Spring Technology:

At the heart of this system are Skyjacker's uniquely engineered 2-stage dual rate long travel coil springs. These springs utilize a progressive rate system that transitions from a first Flex Rate to a second Ride Rate. The first Flex Rate stage provides a comfortable ride while allowing increased articulation during suspension drop (full droop), keeping the coil springs properly seated in the upper mount and maintaining tire contact with the terrain. The second Ride Rate stage engages only after compression past the flex rate, providing additional support when needed.

Complete Component Package:

• Progressive variable rate coil springs with side-specific rear coils engineered for Wrangler JL handling characteristics
• Front and rear bump stop spacers that bolt directly onto axle bump pads to safely control suspension travel
• Extended length sway bar end links (front and rear) with pre-installed HD OEM-style rubber bushings for full articulation capability
• Geometry designed to maintain Electronic Stability Control (ESC) functionality within factory parameters

This component box is specifically engineered for the Wrangler JL platform, ensuring proper fitment and performance. The side-specific rear coils and carefully calibrated spring rates work in harmony with the JL's unique suspension geometry to deliver exceptional off-road capability without sacrificing on-road manners.
