Keep your Mercedes-Benz's rear suspension properly located with the Mevotech Supreme Lateral Arm CMS101361. This rear lateral arm installs as a direct-fit replacement for many Mercedes-Benz models, among them the 2015-2024 Mercedes-Benz GLA250, 2013-2019 Mercedes-Benz B250 and 2014-2019 Mercedes-Benz CLA250 — see the "Vehicles it fits" section for the full list and engine-level fitment.
A rear lateral arm is a suspension link that helps locate the wheel and control its side-to-side movement, working to keep the wheel positioned so alignment and handling stay stable. Worn or damaged arms can show up as clunking or knocking over bumps, uneven tire wear, or an alignment that won't hold. If a failed lateral arm is the cause, this unit replaces it.
- Resists corrosion: A protective surface treatment helps prevent rust build-up and increase longevity.
- Rear suspension link: Helps position the wheel and control lateral movement for steady handling.
- Direct-fit replacement: Installs on the listed Mercedes-Benz applications.
Suspension links work in pairs across the axle — inspect the opposite side and related components, and have the vehicle aligned after installation.
