Keep the front wheel precisely located and steering response tight with the Mevotech Supreme Suspension Control Arm and Ball Joint Assembly CMS401277 — a direct-fit F-150 control arm for the front right lower position, built to replace the original on the 2017-2020 Ford F-150. Engineered in-house with application-specific upgrades, the Supreme line is made for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks, with Labor Saver designs and hardware that speed up the install.

Key features:

  • Superior toughness: sintered bearings for longer-lasting performance.
  • Longer service life: added surface treatment helps prevent rust build-up on the ball joint.
  • Simple to service: includes a 180-degree SAE grease fitting.
  • Locked-in fit: added knurling locks the control arm bushing to the sub-frame.
  • Faster fit: a part-specific nylon locking nut is provided.

Cast aluminum construction built to OE-level tolerances. This assembly ties the front lower suspension to the steering knuckle and pivots as the wheel travels; if a worn arm or ball joint is the cause of clunking or loose steering, replacing it with this Mevotech Supreme suspension control arm restores that connection. See the Buyer's Guide tab for engine-level fitment.

Frequently Asked Questions

What vehicles does the CMS401277 fit?

It's a direct-fit replacement for the 2017-2020 Ford F-150, front right lower position. Check the Buyer's Guide tab to confirm engine-level fitment for your truck.

Is this a complete control arm and ball joint assembly?

Yes. The ball joint is pre-assembled into the arm, so you replace the Ford F-150 control arm and its ball joint as one unit rather than pressing in a separate joint.

Is the ball joint greaseable?

Yes — it includes a 180-degree SAE grease fitting, so you can add grease during routine service.

What is this control arm made of?

Cast aluminum construction, built to OE-level tolerances.

What are the signs this part may need replacing?

Signs may include clunking over the front suspension, wandering or loose steering, and uneven tire wear. Have the cause diagnosed first, since these symptoms can also come from other worn suspension parts.
