Upper A Arm 8.75 Steel Ball Plate Style

The U-B Machine Upper A Arm 8.75 Steel Ball Plate Style (Part No. 15-0832) is a bolt-in tubular control arm designed for GM F-Body vehicles from 1971 to 1981. This upper A arm features an 8.75-inch length with a steel ball joint configuration, finished in black powder coat for corrosion resistance. As a direct bolt-in replacement, it maintains OEM geometry while delivering the durability required for street and track applications requiring suspension geometry correction or worn component replacement.

Weighing 3.96 pounds and measuring 11.2 x 1.2 x 14.35 inches, this control arm integrates into existing Chevrolet F-Body suspension systems without modification. The steel construction with powder-coat finish provides extended service life in varied weather conditions. The ball joint design allows for proper wheel alignment articulation while handling the lateral and vertical loads common to F-Body chassis during acceleration, braking, and cornering. This component is essential for maintaining suspension integrity and front-end geometry precision.

Restorers, enthusiasts, and builders working with first and second-generation Camaros, Firebirds, and other F-Body platforms rely on OEM-specification control arms to preserve handling characteristics and wheel alignment. The 15-0832 addresses wear in the front suspension that develops over decades of use. Proper upper A arm condition is critical for consistent steering response, tire wear management, and suspension travel without binding. This replacement part restores factory suspension performance and is a foundational component for any F-Body front-end refresh or restoration project.
