Control Arm Screw-In Alum Shaft 9-3/4in 10Deg

The Control Arm Screw-In Alum Shaft 9-3/4in 10Deg from ALLSTAR PERFORMANCE is a precision tubular upper control arm engineered for high-performance suspension geometry in racing and off-road applications. Designed for users who demand adjustability and durability—from circle-track competitors to street performance enthusiasts—this component allows fine-tuning of suspension alignment angles for optimized handling characteristics. The screw-in ball joint design enables quick field adjustments without complete component replacement, reducing downtime and maintenance costs on the track or shop floor.

Built from aluminum and steel construction with a black powder-coat finish, this 9.75-inch control arm incorporates a 10-degree screw-in ball joint that delivers precise camber and caster adjustability essential for suspension tuning. The aluminum shaft construction reduces unsprung weight while maintaining structural integrity, and the screw-in ball joint mechanism allows incremental adjustment without the need for shims or bent-arm modifications. The black powder-coat protects against corrosion and abrasion, ensuring longevity in demanding racing environments where vibration, heat cycling, and exposure to track chemicals are constant factors.

This universal control arm is ideal for circle-track racers, road-course competitors, and performance-minded builders who require adjustable suspension geometry. Installation is straightforward for technicians with suspension experience—simply remove the factory control arm and bolt in the screw-in replacement, then adjust the ball joint angle for your desired alignment. ALLSTAR's design ensures compatibility across multiple chassis platforms, making it a versatile choice for chassis builders and race shops standardizing on adjustable suspension components for fleet consistency and customer customization.
