Product Details
This Whiteline Rear Upper Shock Absorber Bushing Kit fits the 1988-1991 GMC R3500. Application note: Suits OEM Shocks Only. Part number W33373. You receive 4 bushings, 2 tubes, an install guide, and grease. It goes on the rear of the vehicle.
The connection between the shock and the control arm or body is only as good as the bushing in it. Worn bushings add play, so a firmer replacement helps the shock do its work. The polyurethane used here deflects much less than the original rubber under the same load.
Installation is rated moderate, with about 1 hour of work listed. Plan on a wheel alignment afterward. Other Whiteline parts we list for the R3500: Ball Joint Boot Kit and Front Sway Bar Mount and Link Bushing Kit.
Features
- Bushing compound: The elastomer formulation is chosen to shrug off oil, grease, ozone, and the elements.
- Bushing material: The bushing material is polyurethane, a firmer choice than rubber.
- Install guide: Whiteline packs an install guide with it.
- Self-lubricating: The bushing carries its own grease supply in internal reservoirs, so it keeps moving freely.
- Grease: Supplied with molybdenum disulfide grease for extended service life.
