Construction & Design

Skyjacker’s coil system is crafted from high-quality materials to withstand the rigors of off-road driving while delivering long-lasting performance. The progressive variable rate springs are engineered with precision to provide a seamless transition between flex and ride rates, ensuring the coils remain seated securely in the upper coil mount throughout suspension travel. This design prevents coil bind and maintains tire contact with the terrain for improved traction and control.

The bump stop spacers and extended sway bar end links are robustly constructed to protect suspension components and allow maximum articulation without compromising stability. The use of heavy-duty OEM style rubber bushings in the sway bar end links reduces noise and vibration while enhancing durability.

Installation & Fitment

This coil system is designed for direct fitment on 2021–2024 Jeep Wrangler models equipped with the 6.4L 392 engine. Installation involves bolting the bump stop spacers onto the axle bump pads and replacing the factory coil springs and sway bar end links with the Skyjacker components. The kit is engineered to work seamlessly with the Wrangler’s factory suspension geometry, requiring no additional modifications to maintain Electronic Stability Control functionality.

Professional installation is recommended to ensure proper setup and alignment, but experienced enthusiasts with the right tools can perform the upgrade with moderate mechanical skills.
