Product Details
This Whiteline Rear Leaf Spring and Shackle Bushing Kit fits the 2001-2010 GMC Sierra 2500 HD. Order it as part number W73821. You receive 12 bushings and 4 tubes. Placement: rear.
On a leaf-sprung vehicle the spring eyes and shackles pivot on bushings, and they take the movement every time the axle moves. Worn rubber lets the axle shift and clunk, and heavy loads speed that up. Polyurethane resists deflection far better than the soft rubber it replaces.
Expect a moderate job of about 2 hours. A wheel alignment is not required. To go with it on the Sierra 2500 HD, see Body Mount Bushing Kit, Front Upper and Lower Control Arm Bushing Kit, and Transmission Mount Bushing.
Features
- Bushing compound: Oil, grease, ozone, and weather do not break down the synthetic elastomer used in the bushings.
- Install guide: Written install instructions are included with the part.
- Self-lubricating: Grease reservoirs inside the bushing feed lubrication as it moves.
- Bushing material: Polyurethane bushings flex far less than rubber ones.
