Product Details
This Whiteline Rear Spring to Saddle Insulator Bushing Kit fits the 1970-1981 Pontiac Firebird. This part is for the rear of the vehicle. In the box: 4 bushings, 2 tubes, and grease. The part number is W73825.
The insulator under a leaf spring takes the weight of the vehicle through its whole life. As it wears down, the spring sits differently on the axle and can allow noise and movement. Polyurethane resists deflection far better than the soft rubber it replaces.
Installation is rated moderate, with about 1 hour of work listed. A wheel alignment is not required. Other Whiteline parts we list for the Firebird: Body Mount Bushing Kit, Ball Joint Boot Kit, and Front Upper and Lower Control Arm Bushing Kit.
Features
- Self-lubricating: Grease reservoirs inside the bushing feed lubrication as it moves.
- Bushing compound: The elastomer formulation is chosen to shrug off oil, grease, ozone, and the elements.
- Install guide: Step-by-step installation instructions come with it.
- Grease: Molybdenum disulfide grease is included to help the parts last.
