Product Details
This Whiteline Rear Upper Outer Control Arm Bushing Kit fits the 1986-1991 Mazda RX-7 Base, Turbo (FC). Part number KCA379. Position: rear. Application note: To hub adds +/- 1.5 degrees Camber. The kit contains 4 bushings and 2 tubes.
Lowering a car or fitting wider tires can push camber out of the range an alignment shop can correct with factory parts. This offset bushing moves the arm's pivot point to give the technician more to work with, while also replacing the soft rubber that was there.
Expect a moderate job of about 2 hours. Get the car aligned once it is back on the ground. We also list 12mm Adjustable Front Camber Bolts, Front Control Arm Lower Inner Front Bushing, and Tie Rod Boot Kit for the RX-7.
Features
- Camber adjustment: Helps keep camber in range so the tire holds its footprint through a corner.
- Grease: Moly grease is supplied to prolong the life of the parts.
- Corrosion protection: A protective plating covers the metal components to guard against corrosion.
- Self-lubricating: Internal grease reservoirs keep the bushing lubricated as it works.
- Finish: A powder coated finish resists corrosion and wear.
- Material: Built from polyurethane.
