3/8 Hi-Tech Pushrod - 7.900 Long

The COMP CAMS 3/8 Hi-Tech Pushrod – 7.900 Long (Part #8473-1) is a precision-engineered valve train component designed for high-performance marine and automotive engine builds. This chromoly pushrod delivers the durability and accuracy required for consistent valve actuation in demanding small-block and big-block applications, where reliable valve timing directly impacts engine efficiency and longevity.

Measuring 7.900 inches in length with a 3/8-inch diameter and 0.135-inch thick wall, this pushrod combines structural rigidity with lightweight design. The chromoly construction resists bending and fatigue under the cyclic stresses of valve operation, while the precision length ensures proper valve clearance geometry. The 0.135-inch wall thickness is engineered to balance strength with minimal mass, reducing inertia and allowing higher RPM capability without sacrificing reliability. COMP CAMS Hi-Tech pushrods are manufactured to exacting tolerances, making them suitable for both naturally aspirated and forced-induction engine combinations.

This component suits engine builders and performance enthusiasts working with classic V8 platforms, vintage inboard marine engines, and modern small-block variants. Whether restoring a period-correct power plant or building a competition engine, proper pushrod selection is critical—undersized or worn pushrods introduce valvetrain noise, erratic timing, and eventual failure. The 7.900-inch length accommodates standard 1.5:1 rocker arm ratios common in traditional hot rod and marine applications, making this a direct replacement for OEM and upgrade applications.

COMP CAMS has earned recognition for precision valve train components across OEM and aftermarket markets. Pushrods are individual units—verify rocker arm type, pushrod length, and diameter specifications against your engine's intake and exhaust valve configuration before ordering to ensure proper fit and clearance.
