Keep your Kia's rear suspension tracking true with the Mevotech Supreme Lateral Arm and Ball Joint Assembly (CMS901123), the rear upper forward locating link with an integrated ball joint. It installs as a direct-fit replacement for the 2006-2010 Kia Optima and 2007-2010 Kia Magentis — see the Buyer's Guide tab for engine-specific coverage. This arm helps locate the rear wheel and control its motion, and the ball joint allows the controlled articulation the suspension needs while cornering and traveling over bumps.
Rear upper forward position: replaces the original lateral arm in the rear upper forward location.
Integrated ball joint: the assembly combines the lateral link with its ball joint, so the pivoting joint is renewed together with the arm.
Resists corrosion: a protective surface treatment helps guard against rust build-up.
Worn lateral arms or a loose ball joint can show up as rear-end clunking, uneven tire wear, or a wandering, imprecise feel. If a failed lateral arm or ball joint is the cause, this assembly replaces it. Sold individually; order two for a complete side-to-side replacement, and have the alignment checked after installation.
