3/8 Hi-Tech Pushrod - 9.100 Long

The 3/8 Hi-Tech Pushrod – 9.100 Long by COMP CAMS (MPN 7920-1) is engineered for serious engine builders and mechanics who demand precision valve train geometry in high-performance applications. Pushrods are critical components that transfer camshaft lobe motion to rocker arms, directly influencing valve timing, lift, and overall engine efficiency. This particular model fills a specific role in small-block and mid-sized engine combinations where stock or mildly modified pushrod lengths fall short of performance requirements.

Manufactured from chromoly steel with 0.080-inch wall thickness, the 3/8 Hi-Tech Pushrod delivers superior strength-to-weight ratio compared to standard steel alternatives. The 0.35-inch diameter provides adequate surface contact area at both the cam follower and rocker arm tip while minimizing reciprocating mass—critical for reducing valvetrain harmonics and preventing pushrod flex at high RPM. Chromoly construction resists fatigue cracking under sustained high-lift, high-rpm operation, making this pushrod ideal for street performance engines, racing applications, and modified hydraulic or solid lifter configurations where valve train stress is elevated.

Mechanics restoring or upgrading vintage small-block platforms—particularly Chevrolet, Ford, and Mopar engines with non-adjustable rockers—will find the 9.100-inch length essential for matching modern cylinder head castings, aftermarket rocker arm ratios, or customized pushrod gallery configurations. Installation requires precise measurement and shimming to achieve correct valve lash and prevent binding; weighing only 0.19 lbs, individual pushrods should be installed as a complete matching set to maintain balanced valve train dynamics. Verify bore centerline-to-rocker pivot distance before ordering to ensure proper fit and optimal performance in your specific engine combination.
