Dorman 521-054 Suspension Control Arm and Ball Joint Assembly - Rear Right Upper Rearward
Dorman 521-054 Rear Right Upper Rearward Control Arm
Dorman 521-054 is a direct replacement suspension control arm and ball joint assembly for specific Hyundai and Kia applications. It is built for the rear right upper rearward position and uses a steel casting/forged control arm with a pre-greased, installed ball joint for consistent suspension movement.
Compatible with 2009-2014 Hyundai Genesis, 2011-2016 Hyundai Equus, and 2015-2017 Kia K900, this assembly is made to restore stable rear suspension geometry and predictable handling. The Dorman 521-054 also includes rubber bushings and mounting hardware for a service-ready replacement.
Key Features
- Direct replacement suspension control arm and ball joint assembly
- Fits the rear right upper rearward suspension position
- Steel control arm with black finish
- Ball joint is installed and pre-greased
- Rubber bushings included
- Mounting hardware included
- Threaded ball joint stud with 14 mm thread diameter
- Pressed attachment type with one mounting hole
Detailed Description
This Dorman suspension control arm assembly is engineered for OE-style fitment on select Hyundai Genesis, Hyundai Equus, and Kia K900 models. The forged/casting steel construction supports light-duty suspension service, while the installed ball joint and rubber bushings help maintain smooth articulation and directional stability. The Dorman 521-054 is a practical replacement when the original rear suspension link shows wear, looseness, or alignment-related issues.
This part cross-references Delphi TC7430 for the same application. It also cross-references Mevotech Supreme CMS90192 for the same application.
Common Issues This Part Can Help Address
- Rear suspension clunking or knocking from worn joints or bushings
- Excessive play in the rear right upper rearward link
- Uneven rear tire wear related to suspension looseness
- Unstable rear-end tracking or wandering during driving
- Alignment problems caused by a worn control arm assembly
Installation Notes and Tips
Verify vehicle fitment by year, make, model, and rear right upper rearward position before installation. Because the ball joint is already installed and the assembly is pre-greased, the part is ready for suspension service once the original component is removed. After installation, a professional wheel alignment is recommended to confirm rear suspension geometry.
Quality Assurance
Dorman uses an industry-focused evaluation process for this replacement assembly to support smooth ride quality, directional stability, and predictable suspension response. The part number is 521-054.
