Product Description

The Energy Suspension 4.4121G Polyurethane Body Mount Set is engineered to replace worn-out OEM rubber mounts on Ford Super Duty trucks with a high-performance Hyper-Flex™ polyurethane solution. Over time, factory rubber body mounts can crack, distort, and collapse, leading to misalignment of the truck's cab and body while reducing ride quality and structural integrity. The specially formulated polyurethane material is tougher than standard rubber, helping maintain proper body-to-frame and cab-to-bed alignment for longer service life. This set is designed for Regular and Super Cab Super Duty trucks, balancing ride comfort with rugged durability.

Compatible with 1999-2007 Ford F-250 and F-350 Super Duty models and 2002-2007 F-450 and F-550 Super Duty trucks in both 2WD and 4WD configurations, the 4.4121G set installs in place of the original bushings. While hardware is not included and OE fasteners should be reused or sourced separately, the polyurethane construction resists road grime and environmental wear significantly better than rubber. This makes it an excellent upgrade for trucks used in daily driving, hauling, towing, or light performance applications.
