3/8 Hi-Tech Pushrod - 8.500 Long

The 3/8 Hi-Tech Pushrod - 8.500 Long from COMP CAMS is engineered for high-performance engine builders and serious enthusiasts who demand precision valve train components. Pushrods are critical mechanical links that transfer motion from the camshaft to the rocker arms, directly influencing valve timing accuracy and engine responsiveness. This 8.500-inch length model is designed for small-block applications where OEM or modified clearances require exact pushrod geometry for optimal valve overlap and cylinder head sealing.

Constructed from chromoly steel with a 0.135-inch thick wall and 3/8-inch diameter, the 3/8 Hi-Tech Pushrod delivers superior strength-to-weight ratio compared to standard pushrods while maintaining rigidity under high-RPM stress. The Hi-Tech designation indicates advanced manufacturing and material selection that resists deflection, a critical concern in street and race engines where valve train harmonics can cause timing loss and reduced power output. Chromoly's fatigue resistance ensures reliability across repeated load cycles, particularly important when running aggressive cam profiles or increased valve spring pressures that stress conventional components.

This pushrod suits builders working on small-block Chevy, Ford, and similar platforms requiring 8.500-inch pushrods for stud-mount or screw-in rocker arm configurations. Proper length selection is critical—too-long pushrods bind during valve opening, restricting lift; too-short designs create excessive clearance and erratic valve action. Installation requires careful measurement and verification against your specific cylinder head and block combination to ensure correct rocker arm geometry and valve lash settings. COMP CAMS pushrods are industry-standard components trusted by engine shops, performance rebuilders, and OEM restoration specialists who prioritize valve train reliability and consistent performance gains.
