Keep your front wheel located and your alignment on-spec with the Mevotech Supreme control arm and ball joint assembly (CMS50191), a direct-fit replacement for the FRONT RIGHT LOWER position on the 2003-2007 Cadillac CTS. This Mevotech Supreme lower control arm links the steering knuckle to the sub-frame, letting the wheel travel through its arc while helping hold the front suspension geometry in place.
- Sintered bearings: engineered for longer-lasting performance.
- Rust-resistant ball joint: additional surface treatment helps prevent rust build-up for a longer ball joint service life.
- Simple to service: includes a 90-degree SAE grease fitting.
- Locked-in fit: added knurling locks the control arm bushing to the sub-frame, while an application-specific ball stud system with a larger sphere and a thicker, stronger flange helps prevent deformation during installation; a part-specific locking nut is included.
Built with cast aluminum construction to OE-level tolerances, this Mevotech Supreme suspension control arm is designed for high-usage passenger vehicles, SUVs, fleets and working trucks. Sold individually; confirm your Cadillac CTS lower control arm application before ordering.
