Construction & Design

The aFe RaceRunner Leveling Rear Coil Springs are crafted from high-quality chrome silicon steel, known for its excellent strength-to-weight ratio and resistance to fatigue. Each spring is cold-formed to ensure consistent dimensions and reliable performance, then heat treated and pre-set to guarantee a stable, constant ride height that resists sagging over time.

This meticulous manufacturing process results in coil springs that maintain their shape and performance even under demanding off-road conditions. The factory-fit design ensures seamless integration with your Jeep’s existing suspension components, preserving ride quality and handling characteristics without compromise.

Installation & Fitment

Installation of the aFe RaceRunner Leveling Rear Coil Springs is straightforward and user-friendly. Designed to match the factory spring configuration, these springs install directly onto the rear suspension of 2018–2026 Jeep Wrangler JL models, including both 2-Door and 4-Door Sport trims. No cutting, welding, or additional modifications are necessary.

They are compatible with both stock shock absorbers and aFe RaceRunner shocks, allowing for flexible suspension upgrade paths. While professional installation is recommended to ensure proper fitment and safety, experienced enthusiasts can perform the swap using standard suspension tools.
