Product Details
This Whiteline Rear Upper Rearward Control Arm Bushing Kit fits the 2016-2025 Mazda MX-5 Miata (ND). Included: 2 bushings and 2 tubes. The part number is W63619. Placement: rear.
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.
Expect a moderate job of about 2 hours. Plan on a wheel alignment afterward. 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
- Install guide: Instructions for fitting are packed in the box.
- Self-lubricating: Internal grease reservoirs keep the bushing lubricated as it works.
- Material: Built from polyurethane.
- Bushing compound: The bushing material stands up to oil, grease, ozone, and weather.
