Keep your rear suspension precisely located with the Mevotech Supreme Lateral Arm CMS901274, a direct-fit replacement for the 2015-2019 Hyundai Sonata and 2016-2020 Kia Optima. This is the rear left upper lateral arm, connecting the knuckle to the chassis to help position the rear wheel and allow controlled suspension movement over the road.
If a worn lateral arm or its ball joint is the source of clunking, imprecise handling, or uneven rear tire wear, this arm replaces it. Sold individually; order the opposite-side arm separately if both need replacement.
