Help keep your steering tight and your front end stable with the Mevotech Supreme Suspension Control Arm and Ball Joint Assembly (CMS401340) — a direct-fit 2020-2023 Ford Ranger control arm. This front left lower unit locates the wheel and, through its integrated ball joint, lets the steering knuckle pivot as you steer and the suspension travels.

  • Superior toughness: sintered bearings deliver longer-lasting performance.
  • Increased stiffness: double-bonded bushings help improve handling and durability.
  • Corrosion protection: a boot built into the ball joint seals out contaminants, and a protective surface treatment resists rust build-up.
  • Simple to service: includes a 90-degree SAE grease fitting plus a part-specific nylon locking nut for a faster ball-joint fit.

Built with stamped steel construction to OE-level tolerances, this Mevotech Supreme lower control arm bolts in as a Mevotech Supreme suspension control arm replacement when the original's bushings, bearings, or ball joint wear out. Signs it may need replacing include clunking over bumps, wandering or loose steering, and uneven tire wear — diagnose the cause first, as these symptoms can have other sources. See the Buyer's Guide tab to confirm your engine.
