3/8 Hi-Tech Pushrods - 8.680 & 9.650 Long

The COMP CAMS 3/8 Hi-Tech Pushrods in 8.680 and 9.650 inch lengths represent precision engine component engineering for Big Block Chevy marine and automotive applications. This set of 16 chromoly pushrods combines lightweight construction with the structural integrity required for high-RPM performance in demanding marine environments where reliability and consistent valve train geometry are non-negotiable.

At 3/8 inch diameter with 0.080 inch wall thickness, these pushrods deliver the strength-to-weight ratio needed for sustained performance in inboard marine engines. Chromoly construction provides superior fatigue resistance compared to standard steel, critical for the constant load cycling in marine powerplants. The dual-length configuration—8.680 and 9.650 inches—accommodates different cam and rocker arm geometries, ensuring proper pushrod angles for optimal valve control and minimal side load on valve stems. This precision fit directly impacts valve sealing, fuel economy, and engine longevity in offshore and freshwater applications.

These pushrods serve serious boaters and marine engine rebuilders who demand OEM-quality valve train components. Whether restoring a vintage marine engine or upgrading a performance inboard, proper pushrod specification is essential to avoid valve float, noise, and premature wear. The set of 16 covers a complete Big Block Chevy valve train configuration, eliminating the need for multiple partial purchases.

COMP CAMS Hi-Tech pushrods are engineered to exacting tolerances and widely recognized within the performance engine community for consistency and durability. When building or maintaining a marine engine, choosing verified component specifications prevents costly mismatches and downtime. TacticalSurplusUSA stocks this set for customers who accept no compromise on engine reliability.
