Coil Spring

This component is crucial for supporting the vehicle's body and chassis while enabling the suspension, wheels, and tires to adapt to road surface variations. The coil springs are constructed from high tensile steel, cold wound with chrome silicon 9254 or hot wound with 5160, and are precisely engineered with appropriate wire diameter to ensure maximum reliability and prevent premature coil bind. These coil springs are built to withstand full coil bind, meaning they can be compressed flat and will return to their original height. They are preset with a hydraulic stress to reduce fatigue in the steel and prevent sagging, ensuring long-term durability. Furthermore, the springs are shot peened to increase tensile strength, allowing for maximum wheel travel without sacrificing spring life. A polyester-based powder coat is applied for enhanced flexibility and durability, protecting against the elements. This specific BDS Suspension coil spring provides a 3-inch lift for 4-door Jeep Wrangler JK models or can be used on 2-door models with a 4-inch lift. It is compatible with 2007-2018 Jeep Wrangler JK models, supporting both 4WD and RWD drivetrains. The product listing encourages users to confirm fitment for their specific vehicle, noting that it fits a wide range of Jeeps and provides a search function for full compatibility.
