Product Description

Restores precise suspension geometry and wheel control by linking the front hub to the subframe while allowing controlled movement through its upper ball joint and bushings.
You’ll typically see it on the Mazda MX-5 (Miata); see our compatibility table or verify fitment using VIN/chassis.
Commonly replaced after curb/impact damage (bent arm), when the ball joint or bushings are worn, or to correct alignment issues and front-end noises.
