3/8 .135 Wall Moly Pushrods - 9.550 Long

The 3/8 .135 Wall Moly Pushrods – 9.550 Long are engineered for high-performance engine builders and serious hot rodders seeking reliable valvetrain control in modified and race applications. Pushrods are the critical mechanical link between the camshaft and rocker arms, converting cam lobe motion into precise valve actuation. These Manley units are designed for engines running elevated RPM, aggressive cam profiles, and solid or hydraulic roller lifter setups where pushrod flex and deflection must be minimized. Whether you're building a street performance engine, small-block Chevy stroker, or all-out competition platform, quality pushrods are non-negotiable for durability and consistent valve timing.

These pushrods feature chromoly construction with a 0.135-inch wall thickness, offering the optimal balance between strength and weight. The 3/8-inch diameter and 9.550-inch length specification fits common small-block engine configurations with standard 1.5:1 rocker arm ratio geometries. Manley's swedged end design ensures precise contact with lifter seats and rocker arm ball seats, reducing binding and wear. Chromoly's superior material properties—higher tensile strength and fatigue resistance compared to standard steel—allow these pushrods to withstand the shock loads generated by high-lift cams, heavy valve springs, and sustained high-RPM operation without catastrophic bending or failure. The set of eight units accommodates a complete eight-cylinder engine.

Builders installing these 9.550-inch pushrods should verify exact engine specifications—deck height, rocker arm ratio, lifter type, and installed valve spring height—before ordering, as incorrect length or diameter creates preload issues and reduces valve control. Manley pushrods are ideal for street engines with performance cam profiles, bracket racing platforms, and customer builds demanding reliability under aggressive tune-up conditions. Installation requires careful valve lash adjustment and pushrod length verification; even small discrepancies compromise valve actuation geometry. These chromoly rods are a trusted choice among engine builders nationwide for repeat customers and shops requiring premium valvetrain components with proven track records.
