Product Details
This Whiteline 15mm Front Sway Bar Bushing Kit fits the 1979-1980 GMC K1500. The chassis code on the listing is C/K. Placement: front. The kit contains 2 bushings. Whiteline part number: W23821.
Sway bar mount bushings work as the bearings of the roll-control system. They need to hold the bar firmly without binding, and they have to cope with constant twisting. A new set restores that balance and quiets the knocks that worn ones make.
Whiteline rates the install as moderate and lists about 1 hour. No alignment is needed afterward. To go with it on the K1500, see Transmission Mount Bushing Kit and Body Mount and Radiator Support Bushing Kit.
Features
- Bushing compound: A synthetic elastomer compound resists oil, grease, ozone, and weathering.
- Self-lubricating: Internal grease reservoirs keep the bushing lubricated as it works.
- Install guide: An install guide comes in the box.
