Custom tune the spring rate and ride height of your 4-inch lifted 2005-2026 gas Ford F-250 or F-350 Super Duty 4WD by swapping coil springs. A critical part of your vehicle's suspension, BDS coil springs support the weight of your truck's body and chassis while your suspension, wheels and tires follow changes in road surface.

Manufactured from high tensile steel, our direct OE replacement coil springs are engineered with properly sized wire diameter. This results in maximum reliability without premature coil bind.

• Designed to withstand full coil bind: you can smash our coils to totally flat and they will return to their original height
• A polyester-based powder coat is applied to ensure flexibility and durability
• Preset with a hydraulic stress to reduce fatigue in the steel and prevent sagging
• Shot peened to increase tensile strength and maximum wheel travel without sacrificing spring life
• Either cold wound with chrome silicon 9254 or hot wound with 5160 to guarantee long life
