Rear Spring Bushing Set

The Energy Suspension Rear Spring Bushing Set (5.2118G) is a polyurethane-and-steel replacement bushing kit engineered for Dodge Ram full-size trucks from 2003 to 2009. This Hyper-Flex suspension component replaces factory rubber leaf spring bushings with high-performance elastomer material, restoring worn articulation and eliminating the sagging rear that commonly develops in aging Ram trucks. The black polymer construction paired with cadmium-plated steel hardware delivers both durability and corrosion resistance in harsh road environments.

Energy Suspension's Hyper-Flex polyurethane formulation resists UV degradation and temperature cycling far better than original rubber, maintaining load support and bushing articulation over extended service life. The rear spring bushing set addresses a critical maintenance point in Ram 2500 and 3500 trucks, where factory bushings deteriorate under the load demands of towing and payload capacity. Replacing worn bushings eliminates clunking noises from the rear suspension, improves axle alignment stability, and restores proper ride height. The cadmium plating protects steel components from rust, important for vehicles operating in wet or salt-air environments where corrosion accelerates bushing failure.

This kit is the preferred choice for Ram truck owners performing preventative suspension maintenance or repairing suspension noise caused by bushing wear. Whether maintaining a work truck, restoring a aging Ram, or rebuilding the rear suspension on a higher-mileage vehicle, this Energy Suspension bushing set provides a direct factory replacement that performs beyond OEM specifications. Installation requires basic suspension work—typical applications involve removing the leaf spring from the frame, pressing out old bushings, and installing the new polyurethane components using the existing hardware.
