3/8 .135 Wall Moly Pushrod - 9.150 Long

The MANLEY 3/8 .135 Wall Moly Pushrod – 9.150 Long (MPN 25362-1) is a precision chromoly component engineered for high-performance engine applications demanding reliable valve actuation. This 9.150-inch pushrod combines a 3/8-inch diameter with 0.135-inch wall thickness, delivering the strength-to-weight ratio critical for sustained RPM stability and reduced valve train wear. Designed with swedged ends for secure seating, this moly pushrod resists galling and maintains dimensional consistency through thousands of heat cycles—essential in marine engines and high-output automotive builds where thermal cycling and pressure spikes are constant.

The chromoly material composition provides superior strength compared to standard steel pushrods while keeping overall weight low—a critical balance in valve train design. The 0.135-inch wall thickness is engineered to handle the stresses of aggressive cam profiles and high valve spring pressures without flexing, which would compromise valve timing precision. The swedged ends ensure positive engagement with rocker arms and lifters, eliminating slippage under high-load conditions. This specification makes the pushrod suitable for both stock performance upgrades and fully built engines operating at elevated boost or rpm levels.

This pushrod is purpose-built for engine builders and rebuilders who need a single replacement component that meets OEM clearances while offering superior durability. It serves as both a direct replacement in stock-spec applications and a baseline component in custom engine builds where valve train geometry is matched to a specific block, head, and camshaft combination. At 0.26 lbs, it contributes minimal rotating mass to the overall valve train assembly, supporting consistent power delivery across the RPM band.

MANLEY pushrods are known in the engine-building community for tight tolerances and consistent performance, making this component a reliable choice for builders who prioritize long-term reliability over cost cutting. Whether you're refreshing a tired engine or assembling a fresh short block, the 3/8 .135 Wall Moly Pushrod ensures that valve actuation remains crisp and predictable through the entire service life.
