Output Shaft

The BRINN Transmission Output Shaft (Part Number 74010) is a heavy-duty steel transmission component engineered for high-performance and drag racing applications. This output shaft serves as the critical link between the transmission's gear train and the driveline, transferring engine torque to the wheels with minimal power loss. Designed to handle extreme loads and sustained high RPM operation, the Brinn output shaft is a proven choice for builders seeking reliable power delivery in custom transmission builds.

Manufactured from steel for superior strength and fatigue resistance, this output shaft measures 24 inches in length with a 4.5-inch outer diameter, providing a robust mechanical interface for driveline connection. The shaft's dimensions and construction are optimized to accommodate the rotational forces and shock loads typical of performance transmission operation. At 5.74 pounds, the component offers the mass needed for inertia and durability without unnecessary weight penalty. Proper installation requires precise alignment and secure fastening to prevent vibration and ensure consistent engagement with the driveline components.

This Brinn output shaft is intended for custom transmission builders, drag racers, and performance enthusiasts who rely on Brinn's modular transmission platform for competition or extreme duty use. Whether upgrading an existing Brinn transmission assembly or completing a fresh build, this shaft provides the structural integrity needed for consistent, predictable power transfer. Verification of fitment with your specific transmission case, bearing assembly, and driveline configuration is essential before installation to ensure proper clearance and load capacity.
