The 13in. x 5in. x 425# rear spring is designed for vehicles that require enhanced load-carrying capacity and improved suspension geometry. This component is essential for trucks, trailers, and heavy-duty platforms where original equipment manufacturer (OEM) springs may fail under custom modifications or heavy loads. It helps restore proper ride height and maintain axle alignment, preventing sagging that can lead to handling issues and accelerated tire wear.
With a load rating of 425 pounds, this leaf spring is engineered to deliver consistent spring rate throughout the suspension travel range. It is constructed from heat-treated steel, which provides controlled flex characteristics to absorb impacts while maintaining axle control and stability during acceleration and braking. This ensures that the spring resists permanent deformation even under cyclic loading from rough terrain or towing.
Ideal for mechanics and vehicle owners, this rear spring is perfect for restoring factory suspension geometry on work trucks, utility vehicles, or custom builds that carry heavy loads. Installation requires the removal of the existing spring, making it a straightforward upgrade for those looking to enhance their vehicle's performance and load capacity.
