Dorman heavy-duty coil springs are designed to provide a 35 percent increase in load handling capability over the vehicle's nominal spring rate, offering an easy upgrade for vehicles used in continuous heavy hauling conditions. Custom-engineered to improve ride quality, reduce driver fatigue, and improve handling, they're an ideal replacement for coil springs on many pickup trucks, SUVs, RVs, plow trucks, vans and more. They also feature quality steel manufacturing to help ensure reliable performance as replacements or upgrades for worn or damaged originals. Heavy-duty springs are a great compromise between the factory original comfort and stiffer ride from severe heavy-duty models for all-out hauling. Give your hauler new life and capabilities with the Dorman heavy-duty coil springs designed to fit your application.
