Upper A-Arm 8in 13 deg Alum Shaft

The Upper A-Arm 8in 13 deg Alum Shaft (PPM6080S) from PPM Racing Products is a precision-engineered suspension component designed for vehicles requiring custom geometry tuning on road course and competition builds. Built for fabricators, race engineers, and dedicated enthusiasts who demand OEM-quality construction in aftermarket form, this aluminum upper control arm delivers the geometry control necessary for advanced suspension setups where factory arms fall short. Whether you're dialing in camber for track days or building a full independent front suspension system, this component serves as the foundation for responsive handling and consistent tire contact.

Manufactured from lightweight aluminum, the 8-inch arm with 13-degree integrated shaft geometry optimizes suspension kinematics for improved cornering performance and reduced unsprung mass. The 13-degree angle is calculated to work within modern suspension geometry packages, affecting camber curves and instant center location—critical variables that determine how your vehicle's suspension responds under cornering loads. At just 3.07 lbs, the aluminum construction cuts weight compared to steel alternatives while maintaining structural rigidity necessary for high-g cornering and bump compliance. PPM Racing's manufacturing tolerances ensure consistent ball joint interface geometry, enabling proper bump steer control and predictable suspension behavior across the full range of suspension travel.

This upper control arm excels in custom independent suspension applications, bolt-on geometry upgrades for modern platforms, and race car fabrication where suspension architecture demands precision. Installers should verify vehicle-specific ball joint sizing and mounting dimensions before ordering, as control arm geometry interacts directly with steering response and load transfer characteristics. Proper installation requires correct camber alignment and attention to suspension geometry measurement—improper setup can result in uneven tire wear and unwanted handling traits. Ideal for fabricators building custom suspensions, race teams optimizing platform dynamics, and shops specializing in advanced vehicle modifications.
