5/16 Moly Pushrods - 6.500 Long

The MANLEY 5/16 Moly Pushrods – 6.500 Long (Part No. 25650-16) are precision-engineered engine components designed for high-performance small-block and mid-block applications requiring strict dimensional and metallurgical tolerances. Built from chromoly steel with a 0.080-inch thick wall construction, these pushrods deliver the durability and consistency demanded in racing, high-output street engines, and demanding performance builds where valve train reliability is non-negotiable.

Each set includes 16 pushrods featuring swedged ends for secure retention in rocker arm sockets and lifter bores. The 5/16-inch diameter and 6.500-inch length are tailored for specific engine architectures; these dimensions directly impact rocker geometry, valvetrain geometry alignment, and the clearance envelope within the engine bay. Chromoly's superior tensile strength compared to mild steel handles sustained high RPM cycles and dynamic loading without permanent deflection, which translates to consistent valve timing across the entire power band. The moly content enhances strength-to-weight ratio—a critical advantage in engines running elevated lift and spring pressures.

MANLEY's reputation in performance engine components is built on manufacturing consistency and material integrity. These pushrods suit builders and engine shops working with small-block Chevrolet, Ford, Mopar platforms and comparable architectures where OEM pushrod lengths and diameters have been verified against the target engine and valvetrain package. Buyers should confirm application fitment against their specific engine, rocker arm system, and lifter configuration before ordering, as pushrod length and diameter are application-critical dimensions that cannot be modified in the field.

Whether assembling a race engine, rebuilding a performance street motor, or replacing worn original equipment, MANLEY 5/16 moly pushrods are engineered to strict tolerances and material specifications. This 16-piece set provides a complete valvetrain set for dual overhead or single overhead engine architectures, ensuring uniform push-rod performance across all cylinders.
