Summary: The Energy Suspension Rear Leaf Spring Bushing set is engineered to restore and enhance the suspension performance of your GMC K3500. By replacing worn, soft OEM rubber with high-performance Red Hyper-Flex™ Polyurethane, these bushings eliminate the instability and sag often associated with aging suspension components. This upgrade ensures your vehicle remains in control during heavy hauling, braking, and maneuvering while lasting 5 to 10 times longer than conventional rubber. The vibrant Red color provides a performance-focused aesthetic suitable for both restoration and racing applications.
