3/8in Moly Pushrods - 8.550in Long

The 3/8in Moly Pushrods - 8.550in Long by MANLEY are precision-engineered components designed for high-performance engine builds where reliability and durability under extreme valve train stress are non-negotiable. These pushrods serve as the critical mechanical link between your rocker arms and lifters, transmitting motion with zero deflection across the entire rev range. Whether you're building a street performance engine, race-ready small block, or big block application, MANLEY's molybdenum construction delivers the strength and consistency required for forced induction, high-lift cam profiles, and sustained high-RPM operation.

Molybdenum pushrods offer superior strength-to-weight characteristics compared to standard steel alternatives, reducing reciprocating mass while maintaining structural integrity under aggressive valve train loading. The 3/8-inch diameter provides optimal wall thickness and rigidity for demanding applications, while the 8.550-inch length is sized for precise fitment in engines where OEM geometry demands exact dimensions. MANLEY's manufacturing tolerances ensure consistent wall concentricity and straightness—critical factors that prevent binding, minimize deflection, and eliminate noise during operation.

These solid body pushrods are ideal for builders and mechanics upgrading cam profiles, increasing rocker arm pressures, or modifying cam timing. The molybdenum alloy resists galling and wear at both ends, extending service life even in applications running higher rocker arm pressures or modified cam timing. With their precision design, these pushrods are compatible with both hydraulic and mechanical lifters, making them a versatile choice for high-performance engine builds.
