3/8in Moly Pushrods - 8.700in Long

The 3/8in Moly Pushrods - 8.700in Long set represents a critical upgrade for serious engine builders and high-performance enthusiasts tackling small-block and mid-displacement applications. These chromoly pushrods replace stock stamped steel units and are designed for cam-driven valve train systems where durability, reduced flex, and consistent geometry matter under sustained RPM and load. Whether you're rebuilding a vintage muscle car engine, upgrading a street performance build, or preparing for road racing duty, quality pushrods maintain precise valve timing and prevent the deflection that causes reliability issues in modified engines.

Each 3/8in Moly Pushrod in this set features chromoly construction with 0.080 inch wall thickness, offering superior strength-to-weight ratio compared to hollow stamped alternatives. The 8.700 inch length accommodates common small-block geometries with standard rocker ratios and standard or aftermarket cylinder head packages. Swedged ends ensure proper seating in both the lifter and rocker arm, eliminating wear from movement and maintaining clearance during full valve lift events. This thickness and material specification prevents flex under high valve spring loads and extended throttle applications—critical when running performance cams, upgraded springs, or higher engine speeds.

These pushrods suit mechanical flat-tappet cam builds, modern roller cam upgrades, and street or strip engines where reliability and repeatability are non-negotiable. The set of eight handles most inline small-block and mid-size V8 configurations; verify your application's pushrod diameter and length before purchase, as incorrect length creates valve train geometry errors and binding. Installation requires careful length checking and lifter bore alignment, tasks standard for any engine rebuild. Quality pushrods like these maximize the benefit of high-performance heads, cams, and induction systems by ensuring the valve train operates exactly as intended, shot after shot.
