Product Details

This Whiteline Transmission Mount Bushing Kit fits the 1975-1978 GMC C15 Suburban (C/K). Whiteline part number: W93467. You receive 1 mount, 4 washers, 2 nuts, and 2 bolts. Application note: Replaces 1 bolt and 2 bolt style mounts.

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. The polyurethane used here deflects much less than the original rubber under the same load.

Whiteline rates the install as moderate and lists about 1 hour. A wheel alignment is not required. To go with it on the C15 Suburban, see Front Upper and Lower Control Arm Bushing Kit and Tie Rod Boot Kit.

Features

  • Self-lubricating: Internal grease reservoirs keep the bushing lubricated as it works.
  • Bushing material: Polyurethane is firmer than the factory rubber, so it deflects less under load.
  • Install guide: Whiteline packs an install guide with it.
  • Bushing compound: A synthetic elastomer compound resists oil, grease, ozone, and weathering.
  • Grease: Molybdenum disulfide grease is included to help the parts last.
  • Hardware: Supplied with mounting hardware.
