7/16 Moly Pushrod - 8.400 Long

The 7/16 Moly Pushrod - 8.400 Long from MANLEY is a precision-engineered valve train component designed for high-performance and modified engine builds. This pushrod serves as the critical link between a camshaft and rocker arm, translating cam lift into precise valve actuation. Serious engine builders and mechanics rely on quality pushrods to maintain valve timing accuracy and prevent valvetrain flex under aggressive RPM and load conditions. Whether you're upgrading a street performer or race engine, the right pushrod specification is essential to converting cam profile intent into repeatable, reliable valve motion.

This pushrod features a 7/16-inch diameter with 0.165-inch thick wall construction in chromoly (molybdenum alloy steel), delivering superior strength-to-weight ratio and fatigue resistance compared to standard steel alternatives. The swedged end design—a tapered, precision-formed termination—ensures solid contact with both the lifter and rocker arm without binding or chatter. At 8.400 inches long, this specification fits common small-block and mid-displacement engine platforms requiring this exact length to maintain proper valve lash and geometric angles. MANLEY's manufacturing process guarantees dimensional consistency and straightness critical for valvetrain stability at high RPM.

Mechanics and engine builders upgrading to roller rockers, aggressive cam profiles, or higher-RPM operation will benefit from MANLEY's enhanced durability and precision. The moly construction resists deflection under sustained load, preventing the valvetrain noise and timing drift that occurs with inferior pushrods on modified engines. Verify your engine's specific pushrod length and diameter requirement before purchase; incorrect length will cause binding, valve noise, or improper valve timing. Installation requires careful setup of valve lash and pushrod straightness inspection to achieve reliable performance in competition or street applications.
