Product Details
This Whiteline Rear Upper Outer Rearward Control Arm Bushing Kit fits the 2016-2026 Mazda MX-5 Miata (ND). The part number is W63613. This part is for the rear of the vehicle. You receive 2 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. The polyurethane used here deflects much less than the original rubber under the same load.
Installation is rated difficult, with about 3 hours of work listed. An alignment is required after installation. Other Whiteline parts we list for the MX-5 Miata: Rear Sway Bar Link, Adjustable Front Sway Bar Link, and Front and Rear Sway Bar Kit.
Features
- Bushing compound: Oil, grease, ozone, and weather do not break down the synthetic elastomer used in the bushings.
- Self-lubricating: The bushing carries its own grease supply in internal reservoirs, so it keeps moving freely.
- Install guide: Step-by-step installation instructions come with it.
- Material: Built from polyurethane.
