Product Details
This Whiteline Rear Upper and Lower Control Arm Bushing Kit fits the 1984-1996 Chevrolet Corvette (C4). Position: rear. The part number is W63636. The kit contains 16 bushings, 8 tubes, and grease.
A control arm bushing is the pivot where the arm joins the chassis or the wheel carrier. Factory rubber is chosen for quiet and comfort, so it squashes under braking, acceleration, and cornering and lets the arm move more than it should. A firmer replacement keeps the arm where it belongs, which steadies the alignment and gives the car a more consistent feel. Polyurethane resists deflection far better than the soft rubber it replaces.
Installation is rated difficult, with about 2 hours of work listed. Plan on a wheel alignment afterward. Other Whiteline parts we list for the Corvette: Ball Joint Boot Kit, Front Upper and Lower Control Arm Bushing Kit, and Rear Differential Mount Bushing Kit.
Features
- Grease: Molybdenum disulfide grease comes with it for a longer service life.
- Bushing compound: The elastomer formulation is chosen to shrug off oil, grease, ozone, and the elements.
- Install guide: Written install instructions are included with the part.
- Self-lubricating: The bushing carries its own grease supply in internal reservoirs, so it keeps moving freely.
- Bushing material: The bushing material is polyurethane, a firmer choice than rubber.
- Material: Built from polyurethane.
