Control Arm Screw-In Alum Shaft 8-1/4in 10Deg

The Control Arm Screw-In Alum Shaft 8-1/4in 10Deg from ALLSTAR PERFORMANCE is a precision-engineered upper control arm designed for serious suspension tuning and high-performance vehicle modifications. Built for mechanics and enthusiasts who demand adjustability and durability, this tubular aluminum shaft delivers the geometry correction needed for track-focused setups, wheel alignment optimization, and suspension geometry changes. Whether you're dialing in a custom chassis or fine-tuning camber curves on a dedicated platform, this component addresses the core need for accurate upper control arm length and angle adjustment.

Manufactured with an aluminum tube body and steel reinforced pivot points, the 8.25-inch length and 10-degree screw-in ball joint configuration provide both weight savings and structural integrity. The screw-in ball joint design allows for precise preload adjustment and easy replacement without frame removal, reducing downtime during maintenance or geometry changes. Black powder coat finishing protects against corrosion while maintaining a professional appearance, and the universal mounting pattern ensures compatibility across a wide range of custom and OEM-based platforms. The aluminum-steel hybrid construction balances stiffness with reduced unsprung weight, critical for maintaining responsive handling dynamics.

This control arm excels in applications where camber correction, geometry tuning, or suspension travel optimization is required—from circle-track racing to road racing setups and street performance builds. Installation requires basic suspension knowledge and proper alignment equipment post-installation to validate geometry changes. The modular screw-in ball joint design makes it ideal for builders who anticipate future adjustments or who need to fine-tune suspension geometry throughout a vehicle's development cycle. Verify upper control arm length and ball joint diameter compatibility with your existing mounting points before purchase.
