Rocker Shaft - .625 x 4.090 OAL

The Rocker Shaft - .625 x 4.090 OAL from T AND D MACHINE is a precision-engineered valvetrain component designed for serious engine builders and high-performance mechanics. This rocker shaft serves as the critical pivot point for rocker arms in overhead valve (OHV) small-block engine configurations, ensuring exact fitment and reliability during operation.

Manufactured to exacting tolerances by T AND D MACHINE, this rocker shaft features a .625-inch diameter with a 4.090-inch overall length (OAL). These dimensions are engineered to maintain precise rocker arm geometry and minimize deflection under valve spring pressure, which is crucial for optimal performance in high RPM applications.

This rocker shaft is ideal for small-block Chevrolet, Ford, and Mopar engine platforms commonly found in street performance and racing builds. Proper installation requires careful alignment to ensure the best performance and longevity of the engine's valvetrain system.
