3/8 Hi-Tech Pushrod - 8.700 Long

The COMP Cams 3/8 Hi-Tech Pushrod – 8.700 Long is a precision valve train component engineered for high-performance marine engines where reliability under sustained RPM and load conditions is non-negotiable. Built from chromoly steel with 0.080-inch wall thickness, this 3/8-inch diameter pushrod delivers the strength and dimensional stability required for demanding boating applications, from tournament fishing boats to offshore cruisers where engine performance directly impacts safety and fuel efficiency.

The 8.700-inch length is designed to maintain precise valve timing geometry in small-block marine engines, where even minor variances in pushrod length compromise cam lobe opening and closing events. Chromoly construction offers superior fatigue resistance compared to standard steel, critical in marine powerplants that operate at continuous high RPM for extended periods. The Hi-Tech designation indicates manufacturing tolerances held to tighter specifications, ensuring consistent valve actuation across the engine's operating range—essential for fuel economy, emissions control, and long-term durability in saltwater and freshwater service.

This pushrod suits boaters rebuilding or upgrading small-block marine engines—whether restoring a classic inboard, refreshing a high-mileage powerplant, or assembling a performance build. Replacement purhcases typically occur during full engine overhauls when valve train components are renewed to original specification or upgraded to modern performance standards. COMP Cams' engineering focus on valve train precision makes this component a reliable choice for marine technicians and DIY builders who prioritize engine reliability in demanding saltwater and freshwater environments.
