Ford F-350 Super Duty Leaf spring bushings are the platform-specific and dimensionally specified polyurethane bushing kits used to replace worn rubber bushings at the front eye, rear eye and shackle mounting positions of the rear leaf spring assembly. On leaf spring suspension platforms, the front eye bushing at the chassis mounting pin, the rear eye bushing at the shackle-to-spring interface and the shackle bushings at the chassis mount position are the three pivot points through which the spring articulates as it cycles under load. The condition of the bushing at each position directly affects rear axle longitudinal location, spring articulation smoothness, load handling consistency and the NVH transmitted through the spring mounting system into the chassis.
As leaf spring eye and shackle bushings wear, increasing compliance at the mounting interfaces allows the rear axle to move fore and aft under braking and acceleration, contributing to axle tramp, imprecise handling under load, rear end looseness and the clunking from the spring eye and shackle positions that is one of the most common complaints on high-mileage leaf spring trucks. The leaf spring bushings range covers front and rear greaseable main spring eye bushing kits, rear leaf spring bushing kits in dimensionally specified main eye ID and spring width combinations, spring eye front bushing kits in platform-specific and dimensional variants for RWD and 4WD, spring eye rear bushing kits with dimensional specifications, combined front and rear spring eye bushing kits, rear spring eye and shackle combined kits, rear leaf spring bushing kits for various cab 4WD pickup configurations, rear spring cushions and a bulk universal leaf spring bushing kit. All products are backed by a limited lifetime warranty.
Leaf spring eye and shackle bushings on trucks, SUVs and body-on-frame platforms deteriorate under the sustained longitudinal load cycling, road shock and environmental contamination that rear leaf spring assemblies are subject to throughout the vehicle's service life. On platforms used for towing, hauling or off-road driving, bushing wear is significantly accelerated by the elevated and more frequent load inputs that these applications generate. Worn front eye bushings allow the axle to move rearward under braking in a way that directly affects braking stability and front-to-rear load transfer. Worn rear eye and shackle bushings allow the spring to shift and clunk at its rear mount, reducing the spring's controlled articulation and introducing noise and compliance into the rear mount interface.
Renewing Ford F-350 Super Duty leaf spring eye and shackle bushings with correctly specified polyurethane alternatives restores the correct longitudinal compliance at every spring pivot position, eliminating mount noise, improving axle location precision and delivering more consistent, predictable and stable handling under all load, towing and terrain conditions. Greaseable main spring eye bushing kits convert standard non-maintainable pins to a greaseable design, allowing periodic re-lubrication to extend bush life and prevent future pin seizing.
The Ford F-350 Super Duty leaf spring bushing range includes:
Ford F-350 Super Duty Leaf spring eye and shackle bushing renewal is the most direct and cost-effective repair for the rear end clunking, axle tramp and load handling inconsistency that worn spring mount compliance introduces on high-mileage leaf spring trucks. Renewing the bushings restores correct spring pivot compliance at every mount position, eliminates the fore and aft axle movement that worn front eye bushings allow, and returns the rear suspension to the correct articulation baseline from which consistent, stable and controlled handling under all load conditions is delivered.
Greaseable spring eye bushing kits deliver an additional long-term benefit by converting the spring eye to a maintainable design, allowing the pivot pin to be re-lubricated periodically to prevent seizing and extend the service life of the bushing installation. For shops servicing high-mileage applicable trucks and 4WDs, dimensional bushing kits allow the correct profile to be matched by main eye ID and spring width where a platform-specific kit is not required, providing flexibility across a wide range of leaf spring configurations.
Ford F-350 Super Duty Leaf spring bushing kits are designed for installation at the front eye, rear eye and shackle mounting positions of the leaf spring assembly. Installation times range from under an hour for single position eye bushing kits to three hours for complete rear leaf spring bushing kit installations depending on the platform and number of positions being renewed. Installation guides are available across most products. For additional technical assistance, a dedicated support team is available to confirm correct product selection, main eye ID, spring width and fitment for the specific platform and leaf spring assembly configuration.
Ford F-350 Super Duty Leaf spring bushings are manufactured from high-strength polyurethane engineered to withstand the sustained longitudinal load cycling, road shock and environmental contamination that leaf spring front eye, rear eye and shackle mount positions are subject to in everyday, towing, hauling and off-road use. Polyurethane maintains correct spring pivot compliance for longer than factory rubber alternatives under the elevated and repeated load inputs that leaf spring platforms in working use generate, delivering more consistent axle location and handling stability throughout the service life of the installation. Greaseable bushing kits with maintainable pin hardware extend the service interval further by allowing periodic pin re-lubrication. All products are backed by a limited lifetime warranty.
Ford F-350 Super Duty Leaf spring bushings are a practical solution for:
The right leaf spring bushing kit restores correct spring pivot compliance at every renewed mount position, eliminates rear axle longitudinal movement and mount noise, and delivers consistent, stable and predictable handling under every load and terrain condition.
Explore the full Ford F-350 Super Duty leaf spring bushings range and find the right kit for your vehicle. With front and rear greaseable main spring eye bushing kits, rear leaf spring bushing kits in dimensionally specified main eye ID and spring width combinations, platform-specific front and rear spring eye bushing kits for applicable RWD and 4WD truck and passenger platforms, combined front and rear and eye-and-shackle kits, rear leaf spring bushing kits for standard and extended cab 4WD pickup configurations, rear spring cushions and a bulk universal kit, you can renew every leaf spring mount position accurately and complete every rear spring bushing service with confidence.
