Restore precise steering and suspension performance with Circuit Sports Upper Ball Joints for the Mazda Miata NA. Designed as a direct bolt-on replacement for worn factory ball joints, these units provide a cost-effective solution without requiring replacement of the entire control arm.
Over time, factory ball joints can develop excessive play as dust boots crack and contaminants enter the joint, leading to clunking noises, reduced steering response, and uneven tire wear. Circuit Sports ball joints are manufactured to high standards for improved durability, strength, and front-end precision.
Each ball joint features a serviceable Zerk grease fitting, allowing periodic lubrication to reduce friction, extend service life, and help remove contaminated grease.
Sold as a pair.
Professional wheel alignment is recommended after installation.
