Detailed Description

Dorman 527-418 is engineered as a direct-fit suspension control arm and ball joint assembly for the front right upper location. It is designed for 2021-2025 Cadillac Escalade and Escalade ESV, 2019-2025 Chevrolet Silverado 1500, 2021-2025 Chevrolet Tahoe, 2019-2025 GMC Sierra 1500, 2021-2025 GMC Yukon and Yukon XL, plus 2022 Chevrolet Silverado 1500 LTD, 2022 Chevrolet Silverado 1500 Nueva, and 2022 GMC Sierra 1500 Limited. This part cross-references MOOG Chassis Products RK624001 for the same application.

The assembly uses an aluminum control arm with a casting/forged construction, pre-greased ball joint, and included bushings to support predictable suspension movement. Dorman’s evaluation process is used to verify ride quality, directional stability, and consistent handling characteristics for the intended vehicle applications.

What It Helps Address

• Clunking or looseness from a worn upper control arm assembly
• Uneven steering feel or wandering at the front end
• Suspension noise caused by deteriorated bushings or ball joint wear
• Loss of alignment stability after component fatigue
• Front right upper suspension wear on Silverado 1500, Sierra 1500, Tahoe, Yukon, and Escalade models

Installation Notes and Tips

Verify vehicle trim, model year, and front right upper position before installation. Because this assembly is not adjustable, final alignment should be checked after replacement. Confirm the threaded ball joint stud and 12 mm thread diameter match the original suspension setup on the vehicle.

Quality Assurance

Dorman designs this control arm and ball joint assembly as a standard replacement part for specific OE applications. The product is evaluated to support smooth ride quality, directional stability, and predictable suspension dynamics in the intended fitments.
