Control Arm Screw-In Alum Shaft 8in 10Deg

The Control Arm Screw-In Alum Shaft 8in 10Deg is a precision tubular upper control arm engineered for high-performance suspension geometry in competition and off-road vehicles. Designed for users who demand repeatable, adjustable suspension tuning, this component allows precise camber and caster adjustments through its screw-in ball joint interface. Whether you're building a race car, desert buggy, or street rod, this aluminum control arm delivers the geometric flexibility needed to dial in suspension geometry for optimal tire contact and handling response.

Manufactured from aluminum with a durable black powder-coat finish, the 8-inch tubular shaft combines lightweight construction with corrosion resistance and structural rigidity. The 10-degree screw-in ball joint design enables fine-tuning of suspension angles without requiring complete arm replacement—a critical advantage during setup and seasonal adjustments. The aluminum-to-steel joint construction balances weight savings with load-carrying capacity, while the tubular profile minimizes unsprung mass without sacrificing torsional stiffness necessary for consistent suspension behavior under acceleration, braking, and cornering loads.

Fabricators, suspension technicians, and serious competitors benefit most from the adjustability and build quality of this universal control arm. Installation requires standard suspension tools and proper torque sequencing to ensure joint integrity. The screw-in ball joint mechanism allows geometry correction mid-season without frame-off disassembly, saving significant labor and downtime. Compatible with most independent front suspension architectures, this arm is ideal for applications requiring camber correction, anti-dive tuning, or custom suspension geometry in circle track, drag, road course, and street performance builds.
