Locate the rear wheel and help keep it tracking straight with the Mevotech Supreme control arm (CMS401178), a direct-fit rear lower rearward replacement for the 2012-2018 Ford Focus. This suspension control arm links the rear knuckle to the chassis, positioning the wheel and controlling suspension travel while its bushings absorb road shock so the tire stays planted over bumps and through corners.

  • Resists corrosion: a protective surface treatment helps prevent rust build-up.
  • Application-specific engineering: engineered in-house with upgrades built for high-usage passenger vehicles, SUVs, fleets and working trucks.
  • Labor Saver™ design: innovative designs, tools and hardware help make installation faster and easier.
  • Rigorously tested: extensive in-house and third-party durability testing.

A worn Ford Focus control arm often shows up as clunking or knocking over bumps, loose or wandering steering, and uneven tire wear. If a failed control arm or its bushings are the cause, this Mevotech Supreme unit replaces the original in the rear lower rearward position. Because these arms install as a left/right pair, renewing both sides on a 2012 Ford Focus (or any year in the range) is good practice for balanced handling. Sold individually; order 2 for a complete axle replacement.
