Product Details

This Whiteline Transmission Mount Bushing Kit fits the 1977-1978 GMC K15. You receive 4 bushings, 2 tubes, 2 plates, and an install guide. Whiteline part number: W93470.

Every shift and every throttle change sends torque through the gearbox, and the mount decides how far it can move. Reducing that movement keeps the shifter and driveline more consistent and takes some of the slop out of the car's response. Polyurethane resists deflection far better than the soft rubber it replaces.

Installation is rated moderate, with about 1 hour of work listed. It does not require a wheel alignment. Other Whiteline parts we list for the GMC K15: 15mm Front Sway Bar Bushing Kit and Body Mount and Radiator Support Bushing Kit.

Features

  • Bushing material: Made of polyurethane, which resists deflection better than soft rubber.
  • Bushing compound: A synthetic elastomer compound resists oil, grease, ozone, and weathering.
  • Install guide: Whiteline packs an install guide with it.
  • Grease: Molybdenum disulfide grease is included to help the parts last.
  • Self-lubricating: The bushing carries its own grease supply in internal reservoirs, so it keeps moving freely.
  • Easy to fit: Designed for an easy install with ordinary shop equipment.
