Product Description

The Energy Suspension 4.2134R Rear Leaf Spring Bushings are a performance-grade upgrade designed to refresh the rear suspension on a range of Ford and Mazda pickup trucks equipped with leaf springs. Over time, OEM rubber bushings in the leaf spring and shackle mounts can deteriorate, leading to increased rear suspension play, poor load control, and unwanted vibration. This kit uses durable Hyper-Flex™ polyurethane bushings that resist wear, oil, road grime, and environmental exposure significantly better than stock rubber, helping maintain rear suspension stability and handling precision.

Direct replacement fitment for applications such as the Ford Bronco II (1985-1990), Ford Ranger (1986-1997), and various Mazda B-series trucks ensures proper alignment with existing leaf spring geometry. Molded-in frame shackle bushings and included sleeves simplify installation and improve structural support at critical mounting points. Ideal for truck owners seeking enhanced rear suspension control, improved traction under load, and long-lasting bushing performance compared to rubber OE components.
