Keep your BMW's rear suspension precisely located and tracking straight with the Mevotech Supreme Lateral Arm CMS101473. It drops in as a direct-fit replacement for the 2011-2017 BMW X3 and 2015-2018 BMW X4, serving the rear left upper rearward position. A lateral arm connects the wheel carrier to the chassis and controls side-to-side movement of the suspension, helping hold your rear wheel in its designed alignment for stable, predictable handling and even tire wear.
Signs this arm may need replacing include clunking or knocking from the rear suspension over bumps, loose or wandering handling, and uneven rear tire wear. Diagnose the cause before replacing, and have the rear alignment checked after installation. Sold individually. See the Buyer's Guide tab for engine-level fitment.
