Control Arm Screw-In Alum Shaft 7-1/2in 10Deg

The Control Arm Screw-In Aluminum Shaft 7-1/2in 10Deg from Allstar Performance is a precision suspension component engineered for fabricators, race teams, and serious automotive builders who demand adjustability and durability in their front-end geometry. This screw-in aluminum shaft is designed to replace or complement stock control arms in custom suspension builds, allowing fine-tuned camber and caster adjustments that directly impact handling, tire wear, and cornering grip. Whether you're setting up a track car, hot rod, or performance street machine, this component delivers the precision needed for repeatable, competitive alignment geometry.

Manufactured from lightweight aluminum alloy, the 7-1/2-inch shaft with 10-degree geometry reduction delivers weight savings compared to stock cast iron arms while maintaining structural integrity under dynamic load. The screw-in design allows independent adjustment of arm length and angle without requiring complete reassembly, reducing shop time and enabling quick tuning changes between sessions. The 10-degree angle is critical for controlling unwanted bump steer and optimizing roll center height—factors that separate a car that handles predictably from one that's loose or unstable in corners. Allstar Performance's engineering ensures concentricity and thread quality that won't strip or bind, even under repeated adjustment cycles.

This control arm shaft is ideal for bracket racers, road course competitors, and custom builders who run fabricated or heavily modified suspension systems where adjustability is non-negotiable. Installation requires removal of the existing control arm assembly and careful measurement to ensure proper geometry relative to your frame, wheelbase, and desired roll center. Compatibility depends on your suspension design—verify mounting points, ball joint type, and frame clearance before ordering. Proper alignment setup with a quality alignment rack is essential after installation to lock in your camber, caster, and toe specifications for optimal tire contact and handling balance.
