• Maintains factory ride quality while enhancing suspension articulation

Construction & Design

Skyjacker’s Dual Rate Long Travel Coil Springs are crafted from high-quality steel alloys, engineered for strength and durability under extreme conditions. The progressive dual rate design features a carefully calibrated coil geometry that transitions smoothly between flex and ride rates. This ensures the springs remain seated securely in the upper coil mount or bucket during full articulation, preventing coil displacement and maintaining consistent tire contact with the terrain.

The long travel design accommodates greater suspension droop and compression, allowing for enhanced articulation without sacrificing ride comfort. Each spring is precision wound and heat-treated to provide reliable performance and longevity, even in harsh off-road environments.

Installation & Fitment

These coil springs are a direct fit for the front suspension of 2021–2024 Jeep Wrangler models equipped with the 2.0L Turbo engine and the 2023 Jeep Wrangler 6.4L 392. Installation typically requires standard suspension disassembly and reassembly procedures and can be performed by experienced DIYers or professional installers. No major modifications are necessary, making it a straightforward upgrade to improve lift and suspension performance.
