3/8in Moly Pushrod - 9.250in Long

The 3/8in Moly Pushrod – 9.250in Long is a precision valve train component engineered for high-performance marine and automotive engines where reliability under sustained load is non-negotiable. Built to exact specifications for OEM and performance rebuilds, this pushrod transfers camshaft motion directly to rocker arms, making it critical to valve timing accuracy and engine efficiency. Whether you're restoring a classic inboard engine or upgrading a performance build, a quality pushrod ensures consistent valve actuation across all RPM ranges.

Manufactured by Manley, a name trusted in marine engine performance, this pushrod features a 3/8-inch diameter chromoly construction with 0.080-inch wall thickness and swedged ends that lock securely into cup-style rocker arm sockets and lifter buckets. Chromoly steel offers superior strength-to-weight ratio compared to cast iron, reducing mass while resisting bending and flex under high-load conditions—especially important in high-RPM marine engines where valve train harmonics demand precision. The 9.250-inch length is sized for specific engine platforms; accurate fitment is essential to maintain proper preload and clearances in the valve train geometry.

Anglers and boaters running modified or rebuilt inboards benefit most from Manley pushrod engineering, as marine engines operating under sustained load and variable water conditions demand components that resist fatigue and valve float. Installation requires careful measurement and verification against original equipment specifications—incorrect length compromises rocker arm geometry and can cause premature wear or valve lash issues. Always verify your engine's exact pushrod length and diameter before ordering, and consider having a qualified marine mechanic confirm fitment during reassembly.
