Alum Transmission 2nd Gen. Ball Spline

The Alum Transmission 2nd Gen. Ball Spline from BERT TRANSMISSIONS is designed for serious drag racers, street rod builders, and high-horsepower enthusiasts who require a reliable transmission component for extreme conditions. This precision-engineered ball spline transfers power from the engine to the driveline with minimal parasitic loss, making it essential for vehicles operating at sustained high RPMs or under significant boost levels.

Constructed from aluminum, this component reduces rotating mass compared to steel alternatives, enhancing throttle response and minimizing mechanical drag. The ball spline geometry features precision-ground spherical surfaces that distribute torque loads across multiple contact points, significantly improving wear resistance and longevity under shock loads and aggressive shifting. The 2nd generation design optimizes the tooth profile and ball pocket geometry to handle elevated power levels while maintaining a lightweight advantage.

This component is ideal for dedicated race vehicles and turbo or supercharged street machines, providing the durability and performance needed for high-torque applications. Builders who refuse to compromise on transmission reliability will find that the Alum Transmission 2nd Gen. Ball Spline meets their demands for strength and efficiency in performance builds.
