Product Details
This Whiteline Rear Upper Outer Control Arm Bushing Kit fits the 1987-1990 Mazda RX-7 GXL 2+2 (FC). Included: 4 bushings and 2 tubes. The part number is KCA379. Whiteline's note for this fit: To hub adds +/- 1.5 degrees Camber. Placement: rear.
Camber is the sideways lean of the wheel when viewed from the front. An offset control arm bushing places the pivot slightly off-center, which shifts the wheel's camber by a small, fixed amount without replacing the arm. On a lowered car that is often enough to bring the tires back toward an even footprint.
Whiteline rates the install as moderate and lists about 2 hours. An alignment is required after installation. To go with it on the RX-7, see 12mm Adjustable Front Camber Bolts, Front Control Arm Lower Inner Front Bushing, and Tie Rod Boot Kit.
Features
- Camber adjustment: Aims to keep camber in an effective range as the body rolls.
- Bushing compound: Oil, grease, ozone, and weather do not break down the synthetic elastomer used in the bushings.
- Material: Polyurethane construction.
- Grease: Molybdenum disulfide grease comes with it for a longer service life.
- Corrosion protection: Metal parts are plated to resist rust over the long term.
- Finish: Powder coating covers the metal for protection against chips and rust.
