Throttle Arm 5/16 Billet Black

The Throttle Arm 5/16 Billet Black from KING RACING PRODUCTS is a precision-engineered linkage component designed for high-performance sprint car applications. This throttle arm serves as the critical mechanical bridge between your carburetor or fuel injection throttle body and the driver's pedal input, translating foot pressure into precise fuel delivery control. Sprint racers and weekend warrior mechanics rely on this component for responsive, linear throttle engagement during hard acceleration and mid-corner adjustments.

Machined from solid billet aluminum and finished in durable black anodizing, the Throttle Arm 5/16 Billet Black is built to withstand the vibration, heat cycling, and mechanical stress inherent to competitive racing. The 5/16-inch bore diameter accommodates standard sprint car linkage pins and clevis connections, ensuring compatibility with OEM and aftermarket throttle cable and rod systems. Black anodizing provides corrosion resistance while reducing glare in the engine bay, and the lightweight construction—just 0.05 pounds—contributes to overall weight savings without sacrificing rigidity or fatigue resistance in the aluminum alloy.

Sprint car builders and mechanics benefit most from this throttle arm when tuning throttle response geometry and cable leverage ratios. Installation requires basic mechanical skill: secure the arm to your throttle shaft with the 5/16-inch pin, route your throttle cable or rod through the clevis end, and adjust cable tension to eliminate slack while preventing binding at full lock. Whether you're rebuilding a carbureted four-cylinder, LS, or naturally aspirated V8 sprint car, this KING RACING PRODUCTS arm delivers the durability and precision control that separates consistent qualifying runs from inconsistent fuel delivery.
