Keep the leaf spring located and cushion the ride with the Mevotech Supreme Leaf Spring Bushing MS404136, a direct-fit replacement for the 1980-1997 Ford F-250, the 1997 Ford F-250 HD, and the 1980-1997 Ford F-350. It seats in the front forward, shackle position, isolating the leaf spring eye from the shackle so the spring pivots smoothly while damping road vibration. See the "Vehicles it fits" section for the full engine-level fitment.
- High-grade natural rubber: molded for increased durability while it absorbs vibration and shock at the shackle joint.
- OE-quality fit and performance: engineered to fit and perform like the factory bushing on the listed Ford applications.
- Front forward, shackle position: cataloged for the front leaf spring's forward shackle location.
Over time a leaf spring bushing hardens, cracks, or wears out, which can bring on clunking or squeaking over bumps, added leaf spring movement, and looseness at the shackle. If a worn bushing is the cause, replacing it helps restore a tight, quiet pivot. Diagnose the source of the noise before ordering, and inspect the matching bushing on the opposite side.

What is this leaf spring bushing made of?
It is constructed from high-grade natural rubber for increased durability, absorbing vibration and shock where the leaf spring pivots at the shackle.
Where does this bushing install?
It is cataloged for the front forward, shackle position, isolating the leaf spring eye from the shackle so the spring can pivot.
What are the signs of a worn leaf spring bushing?
Clunking or squeaking over bumps, extra leaf spring movement, and looseness at the shackle may indicate the bushing has hardened, cracked, or worn out.
Should I replace both sides at once?
Inspect the matching bushing on the opposite side. Replacing worn bushings in pairs is good practice for balanced, quiet spring movement.
