Rocker Shaft - .625 x 1.980 OAL

The Rocker Shaft - .625 x 1.980 OAL is a precision-engineered valve train component designed for engine builders and performance enthusiasts. This product is essential for those who require reliable replacements in their engine rebuilds or restorations. It serves as the pivotal axis for rocker arms, translating camshaft lobe motion into synchronized valve opening and closing events.

Manufactured to exacting standards, the rocker shaft features a .625-inch diameter with a 1.980-inch overall length (OAL). These precision dimensions ensure proper fit within rocker arm bores and correct oil gallery alignment. Its small footprint (3.05 x 0.9 x 3.35 inches) allows for seamless integration into compact cylinder head designs.

Engine builders and mechanics trust this rocker shaft for its ability to maintain dimensional stability across thermal cycles. This stability helps prevent wear patterns that could compromise valve timing accuracy and fuel economy. It is particularly beneficial in applications where tight valve lash settings are critical.
