Product Details
This Whiteline Rear Spring Bushing Kit fits the 1967-1974 Chevrolet K20 Pickup. The listing names the Pickup trim. Order it as part number W73477. In the box: 12 bushings, 6 tubes, and grease. It goes on the rear of the vehicle.
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.
Installation is rated moderate, with about 2 hours of work listed. An alignment is required after installation. To go with it on the Chevrolet K20, see Transmission Mount Bushing Kit, Tie Rod Boot Kit, and Body Mount and Radiator Support Bushing Kit.
Features
- Bushing compound: A synthetic elastomer compound resists oil, grease, ozone, and weathering.
- Grease: Molybdenum disulfide grease comes with it for a longer service life.
- Install guide: Whiteline packs an install guide with it.
- Bushing material: Made of polyurethane, which resists deflection better than soft rubber.
- Self-lubricating: Internal grease reservoirs keep the bushing lubricated as it works.
