5/16in Moly Pushrod - 8.650in Long

The 5/16in Moly Pushrod – 8.650in Long from MANLEY is a precision-engineered valve train component designed for high-performance engine builds where durability and consistent valve actuation are non-negotiable. Built for serious enthusiasts and professional engine builders, this pushrod serves as the critical link between your engine's rocker arms and lifters, directly influencing cam profile accuracy and valve lift consistency across the entire RPM range.

Manufactured with moly (molybdenum) construction, this pushrod offers superior strength-to-weight ratio and exceptional resistance to deflection under load—critical when dealing with high-lift cams, aggressive valve springs, or elevated engine speeds. The 5/16-inch diameter provides optimal rigidity for small-block applications while maintaining minimal reciprocating mass, reducing inertial stress on rocker arms and lifters. At 8.650 inches in length, this dimension is purpose-built for specific engine configurations where precise installed height ensures proper valve clearance and eliminates overcenter geometry issues that compromise valve train longevity and performance.

This MANLEY pushrod is ideal for vintage drag racing, street-strip hybrid builds, and enthusiast restorations where reliability under stress matters. Compatibility depends on your specific engine block, head configuration, and rocker arm setup—verify installed height, pushrod cup geometry, and any clearance issues with aftermarket intake manifolds before installation. Weighing just 0.14 lbs, it integrates seamlessly into both traditional solid-lifter and modern hydraulic roller valve train configurations, making it a trusted choice among builders seeking OEM-quality durability with performance-grade precision.
