Construction & Design:

Rancho coil springs are crafted from premium high-strength steel, ensuring robust performance under demanding conditions. The springs undergo shot peening and heat treatment processes to enhance fatigue resistance and longevity. Their progressive rate design means the springs provide a softer initial ride for comfort, while progressively stiffening under heavier loads to maintain vehicle control and stability. The powder-coated finish protects against corrosion, making these springs well-suited for harsh environments and off-road use.

Installation & Fitment:

This coil spring kit is designed for direct fitment on 4-door Jeep Wrangler JL Diesel models, including Rubicon and non-Rubicon trims from 2020 to 2023. Installation is straightforward, with the kit including two rear coil springs and all necessary hardware. No major modifications to the vehicle’s body or fenders are required to accommodate the lift, although aftermarket accessories such as bumpers and winches may influence final ride height. Professional installation is recommended to ensure proper fit and performance.
