Tighten up rear wheel location and steady your suspension with the Mevotech Supreme Lateral Arm (CMS501227), a direct-fit replacement for the listed applications. It fits many vehicles, among them the 2010-2016 Buick LaCrosse, 2013-2019 Cadillac XTS and 2014-2017 Buick Regal. Cataloged for the rear right upper rearward position, this lateral arm helps locate the wheel and maintain suspension geometry through bumps and cornering loads. See the "Vehicles it fits" section for the full list of vehicles and engine-level fitment.
Features:
- Rear right upper rearward position: designed to replace the original lateral arm at this specific corner of the rear suspension.
- Resists corrosion: a protective surface treatment helps prevent rust build-up and increase longevity.
- Direct-fit replacement: drops in on the listed applications and helps maintain proper rear wheel positioning.
A worn lateral arm can allow excess movement in the rear suspension, which may show up as clunking over bumps, changes in rear alignment, or uneven tire wear. If a failed lateral arm is the cause of these symptoms, CMS501227 replaces it. Have an alignment checked after installation.
