Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMS80105
Locate the front wheel and let the suspension pivot smoothly with the Mevotech Supreme control arm CMS801179, a front right lower control arm and ball joint assembly engineered as a direct-fit replacement for the 2011-2014 Subaru Impreza and 2013-2014 Subaru WRX STI. It connects the steering knuckle to the chassis, carries the built-in ball joint, and locates the wheel through every bump and steering input.
Integrated ball joint with castle nut: installs quickly — secure the ball joint to the vehicle with the part-specific castle nut provided.
Cast-aluminum construction: built to OE-level tolerances.
Larger sphere ball stud: an application-specific ball stud system with a larger sphere.
Rust-resistant surface treatment: additional surface treatment that resists rust buildup for longer ball joint life.
Worn bushings or a loose ball joint can show up as clunking over bumps, wandering or loose steering, and uneven front tire wear — signs this front right lower arm may need replacing. Mevotech Supreme parts are engineered in-house with application-specific upgrades and backed by extensive in-house and third-party durability testing. See the Buyer's Guide tab to confirm your exact engine and trim.
