Mevotech engineers its Supreme parts in-house, with upgrades specific to each application for added durability and performance. This Mevotech Supreme suspension control arm links the steering knuckle to the chassis. Its integrated ball joint is the pivot that lets the wheel steer and move with the suspension.
- Resists corrosion: a protective surface treatment helps prevent rust build-up.
- Precise engineering: developed inside and out for durability and straightforward installation.
- Premium materials: Mevotech uses premium materials on all components, aimed at longer part life.
- Rigorous testing: put through extensive in-house and third-party durability testing for strength.
If a worn ball joint or a damaged arm is behind clunking over bumps, loose or wandering steering, or uneven tire wear, this assembly replaces both parts together. Have the suspension inspected to confirm the cause first. Consult the vehicle service information for the correct fasteners and whether they may be reused, and check the alignment after installation.
