Restore factory-level steering precision, stability, and braking performance on your 2016–2025 Mazda MX-5 Miata with the Whiteline Front Upper Control Arm Inner Bushing Kit. Worn factory bushings can cause vague steering, increased body roll, and uneven tire wear.
This premium polyurethane bushing kit replaces the inner bushings on the front upper control arms with Whiteline’s advanced synthetic elastomer material, delivering sharper handling, improved feedback, and long-lasting durability without sacrificing ride quality.

- Complete Kit – Includes 4 bushings and 4 tubes for a full front upper arm refresh
- Easy Installation – Designed with the installer in mind (though rated as Difficult due to press-fit nature)
