3/8 Hi-Tech Pushrod - 7.850 Long

The 3/8 Hi-Tech Pushrod - 7.850 Long is a precision-engineered valve train component designed for high-performance and modified engine builds. Built from chromoly steel with 0.080-inch wall thickness, this pushrod is engineered for small-block applications demanding durability and consistent valve actuation under elevated RPM and boost conditions. Whether you're rebuilding a classic V8, upgrading a stroker, or fine-tuning a street or race engine, this 7.850-inch pushrod provides the structural integrity and dimensional accuracy required for dependable operation.

The 3/8-inch diameter and chromoly construction deliver superior strength-to-weight ratio compared to stock steel pushrods, resisting deflection and flex under sustained load and vibration. The 0.080-inch wall thickness strikes the critical balance between rigidity and mass—thicker walls resist bending during aggressive valve spring pressure, while the tapered profile minimizes reciprocating mass for improved rpm stability and reduced parasitic drag. Hi-Tech manufacturing ensures tight tolerances on length and concentricity, which is essential for maintaining valve lash consistency across the full operating range and preventing premature wear on rocker arms and valve stems.

This pushrod is ideal for hot rodders, engine builders, and performance enthusiasts running small-block Chevrolet, Ford, or Mopar platforms with aftermarket heads, aggressive cams, and elevated spring rates. Verify 7.850-inch length compatibility with your specific cylinder head and block geometry, as pushrod length is critical for rocker arm geometry and pushrod seat wear patterns. Use in conjunction with quality roller lifters, hardened pushrods seats, and properly shimmed rocker arms to maximize valve train reliability during extended high-rpm operation or forced-induction applications.
