Rocker Shaft - Brodix .625 x 4.010 A.O.L.

The Rocker Shaft - Brodix .625 x 4.010 A.O.L. from T&D Machine is a precision-engineered valve train component designed for high-performance engine builds and competition applications. This rocker shaft serves as the critical pivot point for rocker arms in small-block and big-block engines, translating camshaft lobe lift into precise valve actuation.

Manufactured by T&D Machine, this rocker shaft features a .625-inch diameter journal with a 4.010-inch axle-over-length (A.O.L.) specification, ensuring exact fitment within Brodix-pattern heads. The precise tolerances minimize rocker arm deflection and oscillation, reducing parasitic losses and enabling accurate valve control across the RPM range.

This rocker shaft is ideal for engine builders upgrading to high-ratio rocker arms or optimizing valve train geometry for maximum breathing efficiency. Its compatibility with Brodix-pattern heads makes it essential for those looking to enhance performance in high-ratio applications.
