Skyjacker Suspension JL35BLT 3.5" Component Box for Jeep Wrangler JL 4-Door

The Skyjacker JL35BLT 3.5-inch Component Box delivers a comprehensive suspension upgrade specifically engineered for Jeep Wrangler JL 4-door models without Rubicon packages. This complete component kit provides enhanced lift while maintaining proper suspension geometry 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 on-road ride while maximizing articulation during off-road travel. As the suspension drops to full droop, the flex rate expands to keep coil springs properly seated and maintain tire contact with terrain. The 2nd Ride Rate stage engages only during compression past the flex rate, delivering controlled handling under load. Rear coils are side-specific to coordinate with the Wrangler JL's distinctive suspension characteristics.

Complete Component Package Includes:

• Front adjustable track bar with pre-installed HD 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 to safely control suspension travel
• Extended-length front and rear sway bar end links with pre-installed HD OEM-style rubber bushings for full articulation capability

This component box maintains proper suspension geometry to ensure your JL's Electronic Stability Control system continues to function within factory parameters, providing both safety and performance.
