Construction & Design:
Rancho coil springs are manufactured from premium high-strength steel, ensuring they withstand the rigors of off-road driving and heavy-duty use. The springs undergo shot peening, a process that improves fatigue resistance by inducing compressive stresses on the surface. Additionally, heat treatment enhances the metal’s tensile strength and durability, allowing the springs to maintain their shape and performance over time.
The powder-coated finish not only provides an attractive appearance but also offers superior protection against rust and corrosion, critical for vehicles exposed to harsh environments. The corner-specific progressive rate design means each spring is tuned to its position on the vehicle, optimizing ride quality and handling characteristics for both on-road comfort and off-road capability.
Installation & Fitment:
The Rancho Coil Spring Kit includes two front coil springs designed for straightforward installation on 4-door Jeep Wrangler JL Diesel models from 2020 through 2023. Installation typically requires standard suspension tools and mechanical knowledge, with no need for body or fender modifications to accommodate larger tires. However, aftermarket accessories such as bumpers or winches may affect the final ride height.
This kit fits a broad range of Jeep Wrangler Unlimited trims, including the 80th Anniversary, Freedom, High Altitude, Islander, Rubicon, Sahara, Sport, Willys, and their respective 4xe variants. It is engineered to maintain a level stance and consistent ride height across these models, even under heavy loads or towing conditions.
