3/8 Magnum Pushrods - 7.750/8.700 Long

The COMP CAMS 3/8 Magnum Pushrods - 7.750/8.700 Long are precision-engineered valve train components designed for serious enthusiasts building high-performance small-block and big-block engines. These pushrods serve as the critical mechanical link between your camshaft and rocker arms, translating cam lobe motion into valve actuation with reliability and consistency. Selecting the correct pushrod length and diameter is fundamental to ensuring proper valve geometry and maximizing engine longevity.

Manufactured with precision-wall construction, these magnum-style pushrods deliver superior strength and minimal deflection under high-RPM and high-lift camshaft scenarios. The 3/8-inch diameter provides an optimal balance between weight savings and rigidity, reducing parasitic losses while maintaining the structural integrity needed for aggressive valve lift and duration. The hardened steel construction resists wear at the ball and cup contact points, extending pushrod service life across countless heat cycles and high-velocity valve events.

These COMP CAMS pushrods are ideal for Chevrolet small-block and big-block platforms, including LS-series engines. Their availability in both 7.750-inch and 8.700-inch lengths accommodates various block heights, head configurations, and rocker arm geometries. This versatility allows you to dial in the exact valve train geometry your specific engine build demands.
