3/8in Moly Pushrods - 8.950in Long

The MANLEY 3/8in Moly Pushrods – 8.950in Long (Part No. 25895-8) are precision-engineered valvetrain components designed for high-performance marine and automotive engines requiring reliable, consistent pushrod geometry. Built from chromoly steel with 0.080-inch thick walls and swedged ends, this set of eight pushrods delivers the dimensional stability and strength needed in demanding applications where valve timing accuracy and component longevity are non-negotiable.

The 8.950-inch length and 3/8-inch diameter specification suit a specific range of engine configurations, making correct fitment verification essential before purchase. Chromoly construction provides superior strength-to-weight ratio compared to standard steel, reducing inertial mass while maintaining the rigidity required for positive valve actuation. The swedged end design creates a secure, precision fit at both rocker arm and lifter interfaces, minimizing wear and maintaining consistent preload across the valve train. At 1.65 pounds per set, these pushrods support efficient engine operation without excess mass penalty.

Precision pushrods are critical for engines running elevated RPM, aggressive valve timing, or modified cam profiles where factory components may flex or fail under stress. Marine engines, in particular, demand reliable valvetrain geometry to maintain peak combustion efficiency across variable load conditions and extended operating hours. Builders restoring vintage performance equipment, upgrading factory valve trains, or assembling high-output small-block engines depend on exact pushrod length and material specifications to ensure proper valve clearance, rocker arm geometry, and overall engine health.

MANLEY is recognized in the performance engine market for manufacturing precision valvetrain components to exacting tolerances. Before ordering, verify the 8.950-inch length matches your specific engine block, cylinder head, and rocker arm configuration—pushrod length is not universal and incorrect sizing will result in improper valve clearance and engine damage. This set provides eight pieces suitable for V8 applications or partial component replacement.
