Product Details
This Whiteline Transmission Mount Bushing Kit fits the 1977-1978 GMC K25 (C/K). Order it as part number W93470. Included: 4 bushings, 2 tubes, 2 plates, and an install guide.
The transmission is held in the chassis by a mount that absorbs vibration. A soft or worn mount lets the gearbox rock when you shift or get on and off the throttle, which feels like a jerk, a clunk, or a delay. A firmer mount or bushing limits that motion. Polyurethane resists deflection far better than the soft rubber it replaces.
Whiteline rates the install as moderate and lists about 1 hour. No alignment is needed afterward. Other Whiteline parts we list for the GMC K25: 15mm Front Sway Bar Bushing Kit and Body Mount and Radiator Support Bushing Kit.
Features
- Install guide: Written install instructions are included with the part.
- Bushing compound: The bushing material stands up to oil, grease, ozone, and weather.
- Easy to fit: Designed for an easy install with ordinary shop equipment.
- Bushing material: Polyurethane is firmer than the factory rubber, so it deflects less under load.
- Grease: Supplied with molybdenum disulfide grease for extended service life.
- Self-lubricating: The bushing carries its own grease supply in internal reservoirs, so it keeps moving freely.
