Throttle Arm 5/16in

The Throttle Arm 5/16in is a precision-engineered aluminum linkage component designed for high-performance marine and motorsport applications. Built by M AND W ALUMINUM PRODUCTS, this throttle arm is essential for boaters, mechanics, and sprint car operators who demand responsive throttle control and reliable power transfer. Whether you're upgrading a marine engine setup, rebuilding a performance boat's fuel system, or servicing sprint car throttle mechanics, this component delivers the durability and precision required in demanding environments where throttle response directly impacts safety and performance.

Manufactured from natural aluminum, the Throttle Arm 5/16in features a 5/16-inch bore diameter—the industry standard for direct-fit compatibility with most marine carburetor linkage systems and sprint car throttle cable assemblies. The aluminum construction provides an optimal balance of lightweight strength and corrosion resistance, critical for saltwater boating environments and high-vibration engine compartments. With dimensions of 2.85 x 1.15 x 2.9 inches and a featherweight 0.07 lbs, this component integrates seamlessly into existing throttle systems without adding unnecessary weight, while maintaining the rigidity needed to eliminate play and binding under sustained acceleration.

Anglers running performance outboards and boaters with carbureted engines will find this throttle arm essential for smooth, predictable throttle actuation during extended runs. Sprint car builders and street rod enthusiasts rely on M AND W components for their proven fit and finish. Installation is straightforward—verify your existing throttle cable diameter matches the 5/16-inch specification before ordering. This is a direct replacement or upgrade component for carbureted marine engines and motorsport applications where aftermarket throttle linkage refinement improves driveability and reduces throttle lag during critical acceleration.
