5/16in Moly Pushrods - 8.700in Long

The 5/16in Moly Pushrods - 8.700in Long from MANLEY are engineered for serious engine builders and performance enthusiasts who demand reliability in high-revving applications. These pushrods serve as the critical mechanical link between your camshaft and rocker arms, transferring precise valve timing commands throughout the entire rpm range. Whether you're building a street performance engine or preparing a competition platform, quality pushrods are non-negotiable—they directly impact valve control, engine stability, and longevity under sustained boost or high-lift cam profiles.

Constructed with moly (molybdenum) material, these pushrods offer superior strength-to-weight characteristics and exceptional resistance to flexing and deflection compared to standard steel alternatives. The moly composition reduces friction and heat generation at critical pushrod-to-rocker and pushrod-to-lifter interfaces, resulting in more consistent valve actuation and reduced wear on valvetrain components. At 8.700 inches in length with a 5/16-inch diameter, this specification fits a wide range of small-block and mid-block engine platforms commonly found in restoration, modified street, and track applications. The precision manufacturing ensures minimal tolerance stack-up, allowing your lifters and rocker geometry to maintain optimal geometry across the full operating envelope.

Serious engine builders choose MANLEY moly pushrods when upgrading camshafts, installing roller rockers, or increasing valve lift and duration beyond stock parameters. If you're converting to a higher-lift cam, installing a solid or hydraulic roller lifter setup, or pushing rpm limits, these pushrods provide the structural integrity and precision fit required for trouble-free operation. Always verify fitment with your specific engine platform, rocker arm type, and cylinder head configuration before installation—pushrod length, diameter, and material must work harmoniously with your complete valvetrain package to ensure proper preload, clearance, and reliability.
