5/16 H/E Pushrods 9.677 Long

The COMP CAMS 5/16 H/E pushrods 9.677 long are precision-engineered components designed for high-performance engine builds where reliability and consistent valve actuation matter most. These pushrods serve as the critical mechanical link between your rocker arms and lifters, transmitting valve-opening commands with minimal deflection across the entire RPM range. Whether you're assembling a naturally aspirated stroker, a boosted small-block platform, or restoring a classic muscle car engine, this 16-piece set provides the strength and dimensional consistency needed for aggressive cam profiles and high-lift applications.

Manufactured from hardened steel with a 5/16-inch outer diameter, these pushrods offer superior rigidity compared to standard wall-thickness alternatives, reducing harmonic vibration and preventing valve float at sustained high RPM. The 9.677-inch length is engineered for compatibility with high-energy or solid-lifter cam systems, where aggressive ramp rates and higher spring pressures demand components that won't flex under load. COMP CAMS' manufacturing tolerances ensure consistent pushrod length across all 16 units, eliminating the valve lash variances that plague mismatched sets and threaten cylinder-to-cylinder consistency. The steel construction resists fatigue failure even in applications pushing 7,000+ RPM, making these pushrods a non-negotiable upgrade for serious engine work.

These pushrods are ideal for engine builders and performance enthusiasts upgrading to aftermarket cam profiles or increasing valve spring pressure beyond stock tolerances. Installation requires careful clearance verification at both the rocker arm and lifter ends, particularly when modifying deck height or using non-OEM cylinder heads. The universal design works across most small-block and mid-block platforms, though proper fitment checks are essential before final assembly. When paired with a quality high-energy camshaft and adjustable rocker arms, this set delivers the valve control and durability expected from a professional-grade engine rebuild.
