A-Arm 11.00 Screw-In B/J

The A-Arm 11.00 Screw-In B/J is a precision tubular control arm engineered for high-performance suspension geometry on vehicles requiring heavy-duty front-end dynamics. Manufactured by JOES Racing Products, this upper control arm is purpose-built for race teams, off-road platforms, and specialized automotive applications where suspension articulation and load management demand engineered accuracy. The 11-inch length paired with a 10-degree geometry setting positions this arm for specific ride-height and camber corrections that professional builders rely on when dialing in critical suspension tuning.

Constructed from aluminum and steel components with black powder-coat protection, the A-Arm 11.00 Screw-In B/J delivers corrosion resistance and structural integrity under extreme load cycles. The screw-in ball joint design allows for straightforward maintenance and replacement without specialized tooling, a critical advantage during track-side adjustments or rebuild cycles. The tubular construction minimizes weight while maintaining rigidity—a hallmark of JOES Racing Products' engineering approach. The 3.72 lbs weight keeps unsprung mass low, directly improving suspension response and tire contact consistency.

This control arm serves race teams, off-road fabricators, and precision suspension shops building custom or factory-upgrade suspensions. The standard bushing style accommodates both OEM and aftermarket bushing options, allowing builders to tune compliance and NVH characteristics to their specific platform. Proper installation requires alignment verification and geometry confirmation post-installation. The A-Arm 11.00 Screw-In B/J is sold individually and is best paired with a matching lower arm and appropriate ball joint hardware for complete suspension assembly.
