Aluminum Shifter Arm

The aluminum shifter arm is an essential control linkage component for boaters and marine engine builders who demand reliable gear selection under all water conditions. This universal shifter arm accommodates standard 3/8-inch mounting slots and 1/4-inch shifter rod holes, making it compatible with a wide range of marine transmissions and shift systems. Whether you're restoring a classic boat engine, upgrading an existing installation, or building a custom marine power package, this shifter arm provides the mechanical precision needed for smooth, responsive gear engagement from idle to full throttle.

Manufactured from lightweight aluminum and finished in durable black anodized coating, this shifter arm resists corrosion in saltwater and freshwater environments while maintaining dimensional stability over thousands of shift cycles. The 1/4-inch thickness provides adequate structural rigidity to handle the mechanical loads imposed during aggressive gear changes without flex or play. The compact design—measuring just 4 inches long with a 0.45-inch profile—minimizes footprint in tight engine compartments while the precision-drilled mounting and control holes ensure repeatable alignment and calibration of your shift mechanism.

Serious boaters, marine technicians, and performance engine builders rely on this shifter arm for its proven compatibility across Allstar Performance marine packages and aftermarket transmission setups. The universal design allows for straightforward installation into both inboard and outboard shift linkage systems, provided your transmission features the standard 3/8-inch and 1/4-inch hole patterns. If you're troubleshooting sloppy or unresponsive shift feel, or simply restoring worn drivetrain components, this aluminum shifter arm delivers factory-grade control without the factory price tag.
