Throttle Ball Stud Kit 1/4in-28

The Throttle Ball Stud Kit 1/4in-28 is a precision carburetor linkage component designed for engine builders, tuners, and performance mechanics who demand reliable throttle control in custom and high-performance applications. This ball stud serves as the connection point between throttle levers and linkage rods, transferring throttle input smoothly and consistently from the pedal to the carburetor's throttle blades. Whether you're assembling a stroker engine, upgrading a vintage hot rod, or fine-tuning a competition vehicle, a quality ball stud is essential for eliminating slack and ensuring predictable throttle response.

Manufactured by ALLSTAR PERFORMANCE, this ball stud features a 1/4 inch-28 thread pitch and is constructed from steel with cadmium plating for superior corrosion resistance and longevity in engine bay environments. The cadmium finish protects against rust and chemical degradation, critical for components exposed to fuel vapor, moisture, and temperature cycling. The compact design—measuring 3.5 inches in length and weighing just 0.05 lbs—makes it lightweight and easy to install without adding unnecessary mass to your linkage assembly. The ball-end geometry provides a smooth articulation point that reduces binding and wear compared to sharp corners or poorly fitted connections.

This throttle ball stud kit is ideal for single-barrel, two-barrel, and four-barrel carburetor setups where precision linkage tuning matters. It pairs seamlessly with Holley, Edelbrock, Carter, and other popular carburetors that use standard 1/4-28 threaded stud mounting points. Installation is straightforward: thread the stud into the carburetor lever or linkage bracket, then attach your throttle rod using the ball-end socket—no special tools required. For anyone rebuilding a classic engine, installing progressive linkage, or upgrading throttle response in a race car, this ALLSTAR PERFORMANCE kit delivers the durability and precision expected from a trusted performance brand.
