• Progressive Rate Design: Tuned to deliver superior on-road comfort while enhancing off-road articulation and control.
• Maintains Level Stance: Keeps the Jeep balanced and level even under heavy loads or when towing.
• High-Strength Steel Construction: Manufactured from durable steel that is shot peened and heat treated for long-lasting performance.

Construction & Design:

Rancho rear coil springs are crafted from high-strength steel, which undergoes shot peening and heat treatment processes to enhance durability and fatigue resistance. This advanced manufacturing ensures the springs maintain their shape and performance over time, even under demanding off-road conditions or heavy towing scenarios. The powder-coated finish further protects the springs from corrosion, extending their service life and preserving their appearance.

The progressive rate design means the springs provide a softer initial compression for comfort during normal driving, while progressively stiffening under heavier loads or rough terrain to maintain control and stability.

Installation & Fitment:

This coil spring kit is designed for direct fitment on Jeep Wrangler Unlimited 4-door models from 2007 to 2017 and the 2018 Wrangler JK Unlimited. Installation is straightforward, replacing the factory rear coil springs without the need for additional modifications. However, note that aftermarket accessories such as bumpers, sliders, or winches may affect the effective lift height.

Professional installation is recommended to ensure proper fitment and safety, but experienced DIY enthusiasts with the right tools can complete the swap efficiently.
