Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMK8710T
Keep the front suspension tight and the tire tracking true with the Mevotech Supreme Suspension Control Arm and Ball Joint Assembly CMS501277, a direct-fit replacement for the front right lower rearward position on the 2013-2019 Cadillac ATS, 2020-2024 Cadillac CT4, and 2017 Cadillac CTS. This assembly locates the wheel, absorbs road inputs, and carries an integrated ball joint — see the Buyer's Guide tab for the full engine-level fitment.
Premium materials and extensive in-house and third-party durability testing back the assembly's strength and service life. If a worn control arm or failing ball joint is behind clunking or knocking over bumps, loose or wandering steering, or uneven tire wear, this unit replaces it. Suspension components work in pairs — inspect the opposite side and replace as directed by the service procedure for balanced handling.
