Construction & Design

These coil springs are crafted from premium-grade steel, heat-treated to resist fatigue and maintain consistent spring rates over time. The dual rate design means the springs have two distinct coil densities: a softer initial rate for comfort and a firmer secondary rate to support heavier loads and aggressive off-road maneuvers. This engineering approach ensures the springs absorb bumps and impacts effectively while preventing bottoming out during extreme articulation.

Superlift’s manufacturing process includes precise coil winding and rigorous quality control to deliver springs that fit perfectly and perform reliably under demanding conditions. The powder-coated finish protects against corrosion, extending the lifespan of the springs even in harsh environments.

Installation & Fitment

Installation of the Superlift 2.5-inch Lift Dual Rate Coil Springs is straightforward for experienced mechanics and professional installers. They are designed as a direct replacement for the factory rear coil springs on the 2018-2019 Jeep Wrangler JL, requiring no major modifications. However, it is recommended to have a proper alignment performed after installation to ensure optimal handling and tire wear.

These springs work seamlessly with the Jeep’s existing suspension components, preserving ride quality and suspension travel. For best results, pairing with compatible shocks or other suspension upgrades is advised but not mandatory.
