3/8 Hi-Tech Pushrod - 8.680 Long

The COMP CAMS 3/8 Hi-Tech Pushrod — 8.680 Long is an engineered valve train component designed for high-performance small-block and mid-block engine builds. Pushrods are essential links between the camshaft and rocker arms, transmitting precise valve actuation commands from the cam lobe directly to the valve assembly. This 3/8-inch diameter model serves engines requiring lightweight, high-strength push rod geometry for street, strip, and racing applications where valve timing accuracy and durability under sustained RPM loads are non-negotiable.

COMP CAMS Hi-Tech pushrods employ advanced metallurgy and precision manufacturing to minimize flex and harmonics while maximizing strength-to-weight ratio. The 8.680-inch length specification is calibrated for specific block-head combinations, ensuring correct rocker arm geometry and valve lash compliance. The 3/8-inch pushrod diameter balances structural rigidity with reduced mass, allowing faster acceleration and deceleration through the valve train while resisting bending under high-lift cam profiles and aggressive valve spring pressures. This precision-engineered construction prevents valve float at elevated RPMs and maintains consistent pushrod-to-rocker contact, critical for reliable performance in forced-induction, naturally aspirated, and high-revving engine configurations.

Engine builders and performance enthusiasts select this pushrod for LS, small-block Chevy, Ford Windsor, and comparable platforms where the 8.680-inch length aligns with OEM or custom head/block deck heights. Installation requires careful measurement against your specific engine's pushrod length specification — using the correct length prevents valve train geometry errors that compromise performance and reliability. Whether rebuilding a stock engine with upgraded components or assembling a complete stroker or turbo build, the COMP CAMS 3/8 Hi-Tech Pushrod delivers the precision and durability demanded by serious engine builders and performance shops.
