Keep the rear suspension properly located and hold your wheel alignment in check with the Mevotech Supreme Suspension Trailing Arm CMS501319. This is the rear lower trailing arm, and it drops in as a direct-fit replacement across a wide GM crossover lineup — including the 2018-2025 Buick Enclave and Envision, 2017-2019 Buick LaCrosse, 2018-2020 Buick Regal Sportback and Regal TourX, 2019-2025 Cadillac XT4, 2017-2025 Cadillac XT5, 2020-2025 Cadillac XT6, 2018-2023 Chevrolet Traverse, 2024 Chevrolet Traverse Limited, 2019-2025 Chevrolet Blazer, and 2017-2023 GMC Acadia. See the Buyer's Guide tab for the full application and engine list.
- Stronger build: a stamped steel control arm with a thicker cross section for added strength and durability.
- Resists corrosion: a protective surface treatment helps guard against rust build-up.
A trailing arm anchors the rear lower suspension, managing the fore-and-aft movement of the wheel and helping maintain proper geometry as the suspension cycles. If the original arm or its bushings are worn — signs may include clunking or knocking from the rear on acceleration and over bumps, or handling and alignment that feel off — this arm replaces it. Diagnose the cause before ordering, since these symptoms can have other sources.
