The 13in. x 5in. x 450# Rear Spring is a heavy-duty leaf spring assembly designed for vehicle suspension systems that require increased load capacity and ride stiffness. It is ideal for trucks, trailers, and performance vehicles that frequently carry heavy payloads or tow significant weights. This rear spring is essential for maintaining axle control and preserving chassis geometry under stress.
With a spring rate of 450 pounds per inch, this rear spring is engineered to handle demanding conditions while ensuring minimal deflection under heavy loads. The compact dimensions of 5.7 x 5.5 x 14.6 inches and a weight of 11.3 pounds make it suitable for tight rear axle configurations. This design helps control wheel articulation and prevents axle hop during acceleration or hard braking.
This rear spring is particularly beneficial for applications where factory springs fall short of load demands or where a stiffer setup is necessary for performance driving. It pairs effectively with upgraded shocks and other suspension components to enhance overall vehicle handling and stability. Whether upgrading a work truck or tuning a performance build, this rear spring is a reliable choice.
