Bring precise wheel control back to your Cadillac's front end with the Mevotech Supreme control arm CMS501278, a front left lower rearward control arm and ball joint assembly that installs as a direct-fit replacement for the 2013-2019 Cadillac ATS, 2020-2024 Cadillac CT4, and 2017 Cadillac CTS. It locates the front wheel and links it to the chassis through its bushings, while the integrated ball joint lets the steering and suspension move together.

  • Forged aluminum construction: the arm is built from forged aluminum for the listed applications.
  • Longer ball joint life: an additional surface treatment helps resist rust build-up on the ball joint.
  • Precise engineering: innovated inside and out for durability and easier installation, with Labor Saver designs, tools and hardware to speed the job.
  • Rigorous testing: extensive in-house and third-party durability testing.

As a Mevotech Supreme suspension control arm, this unit is engineered in-house with application-specific upgrades and premium materials across its components, part of a line built for high-usage passenger and commercial vehicles. Signs a control arm bushing or ball joint may be worn include clunking over bumps, steering wander, or uneven tire wear; diagnose the cause before replacing.
