Product Details
This Whiteline Rear Upper Outer Control Arm Bushing Kit fits the 1988-1990 Mazda RX-7 GTU (FC). Placement: rear. You receive 4 bushings and 2 tubes. Whiteline's note for this fit: To hub adds +/- 1.5 degrees Camber. Whiteline part number: KCA379.
Most factory control arm bushings are centered and fixed. An offset one is built so the arm sits at a slightly different angle, which changes camber, and the firmer material stops that setting drifting under load.
Installation is rated moderate, with about 2 hours of work listed. Plan on a wheel alignment afterward. Other Whiteline parts we list for the RX-7: 12mm Adjustable Front Camber Bolts, Front Control Arm Lower Inner Front Bushing, and Tie Rod Boot Kit.
Features
- Corrosion protection: A protective plating covers the metal components to guard against corrosion.
- Bushing compound: The elastomer formulation is chosen to shrug off oil, grease, ozone, and the elements.
- Camber adjustment: Helps hold the tire flatter on the road by correcting camber changes through roll.
- Finish: A powder coated finish resists corrosion and wear.
- Grease: Supplied with molybdenum disulfide grease for extended service life.
- Self-lubricating: Internal grease reservoirs keep the bushing lubricated as it works.
