A-Arm 10.50 Screw-In B/J

The A-Arm 10.50 Screw-In B/J from Joe's Racing Products is a precision upper control arm engineered for high-performance suspension geometry and durability under demanding conditions. This component is essential for vehicle platform specialists, fabricators, and operators who require repeatable, tunable suspension architecture—whether for tactical support vehicles, off-road applications, or competition platforms. The 10.5-inch length and 10-degree geometry deliver precise load transfer and alignment control that directly impact handling stability and tire wear patterns.

Constructed from aluminum and steel with a black powder coat finish, the A-Arm 10.50 Screw-In B/J combines weight reduction with corrosion resistance and structural integrity. The screw-in ball joint design allows field-level adjustment and replacement without specialized press equipment, reducing maintenance time and logistics burden in austere environments. The tubular design with standard bushing style geometry maintains compliance in suspension articulation while delivering the rigidity required for precise wheel alignment under cornering loads and dynamic maneuvers.

This control arm is ideal for custom vehicle builds, suspension upgrades, and platform-specific applications where geometry tuning is critical. Installation requires proper alignment equipment and torque specifications to maximize bearing life and suspension performance. The modular screw-in ball joint construction ensures compatibility with standard suspension packages and allows operators to customize geometry based on vehicle weight, load requirements, and operational demands. Weighing 3.69 pounds, the A-Arm 10.50 Screw-In B/J delivers material efficiency without compromising structural performance.
