5/16in Moly Pushrods - 8.600in Long

The 5/16in Moly Pushrods - 8.600in Long (MAN25718-16) are precision engine components designed for high-performance small-block and mid-range V8 builds. These chromoly pushrods transfer valve actuation force from the camshaft to rocker arms with minimal deflection, making them essential for serious engine modifications where stock pushrods fall short. Whether you're building a street performance engine, upgrading a classic hot rod, or tuning a competition platform, quality pushrods are foundational to reliable valve train geometry and responsiveness across the RPM range.

These pushrods feature 5/16-inch diameter chromoly construction with 0.080-inch wall thickness, delivering the rigidity needed to resist bending under high-lift and aggressive cam profiles. The swedged ends—precision-formed bearing surfaces—ensure proper seating at both the lifter cup and rocker arm interface, reducing wear and maintaining critical valve timing accuracy. At 8.600 inches long, this set of 16 pushrods suits many popular small-block configurations, accommodating both traditional flat-tappet and modern roller cam setups. The chromoly alloy offers superior strength-to-weight ratio compared to standard steel, resisting deflection at elevated RPM and extended valve open durations without excessive added mass.

Experienced builders and mechanics rely on pushrods like these when total valve train control is non-negotiable—particularly in applications running high-lift cams, aluminum heads, or aggressive timing events. Proper pushrod length is critical; the 8.600-inch dimension fits most conventional small-block platforms, but always verify against your specific head and block combination before installation. These components are most effective when paired with quality rocker arms, adjustable valvetrain geometry, and thorough pre-assembly inspection to ensure concentricity and correct preload. Installation requires careful measurement and attention to detail; incorrect length or misalignment will result in premature wear and valve train noise or damage.
