Product Details
Fitted to the 2015-2021 Volkswagen Golf/GTI Golf R Base, S, SE: the Whiteline Rear Upper Outer Control Arm Bushing. Trims named on the listing: Base, S, and SE. Position: rear. Chassis code: AU. The part number is W63579. The kit contains 2 shell bushings and 2 tubes.
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.
Expect a moderate job of about 3 hours. Get the car aligned once it is back on the ground. To go with it on the Golf/GTI Golf R, see Heavy Duty Blade Adjustable 22mm Rear Sway Bar.
Features
- Install guide: An install guide comes in the box.
- Bonded design: The bushing is bonded for extra strength under heavy loads.
- Self-lubricating: The bushing carries its own grease supply in internal reservoirs, so it keeps moving freely.
- Material: Polyurethane construction.
- Corrosion protection: Metal parts are plated to resist rust over the long term.
- Bushing compound: Oil, grease, ozone, and weather do not break down the synthetic elastomer used in the bushings.
