3/8 Hi-Tech Pushrod - 8.450 Long

The 3/8 Hi-Tech Pushrod – 8.450 Long by COMP CAMS is engineered for serious engine builders and mechanics seeking reliable valve train geometry in high-performance applications. Whether you're assembling a naturally aspirated stroker, a vintage muscle car rebuild, or a competition engine, this pushrod serves as a critical link between your rocker arms and lifters. Built to withstand the demands of aggressive cam profiles and elevated RPM operation, it delivers the consistency needed for repeatability across cylinder banks and accountability in tuning variables.

COMP CAMS' Hi-Tech design incorporates precision manufacturing and material science to minimize flex and maintain accurate valve lift across the entire rev range. The 3/8-inch diameter offers an optimal balance between strength and weight, reducing inertial losses while resisting bending under high-load conditions typical of roller cam conversions and flat-tappet aggression. At 8.450 inches in length, this pushrod accommodates a wide range of small-block and mid-block engine platforms where factory or aftermarket cylinder head and block configurations demand exact stack-up clearance. The lightweight construction—just 0.18 lbs per unit—contributes to faster valvetrain acceleration and reduced parasitic drag on engine output.

Mechanics and engine builders selecting pushrods must verify precise length against their specific head and block combination to ensure zero clearance and correct geometry; this 8.450-inch unit suits many common street and strip applications but requires validation before installation. Proper pushrod length is non-negotiable—incorrect sizing causes rocker geometry failure, valve float, and catastrophic engine damage. Use this component as part of a complete valve train package, pairing it with quality rocker arms, hardened pushrods seats, and validated cam profiles for maximum reliability and performance longevity in your build.
