5/16 Magnum Pushrod - 7.900 Long

The 5/16 Magnum Pushrod - 7.900 Long from COMP CAMS is a precision valve train component engineered for small block Chevy and GM V6 engines seeking reliable, high-rpm performance. Pushrods are critical mechanical links between the camshaft and rocker arms, transferring lobe lift while maintaining strict valve timing geometry. This 7.9-inch length magnum-series pushrod is designed for builders who demand consistent, repeatable power delivery without compromise—whether you're running a stock rebuild, mild street engine, or aggressive racing application.

Manufactured from chromoly steel with a 5/16-inch diameter and 0.080-inch wall thickness, this pushrod delivers the structural rigidity needed to resist deflection under valve spring pressure and high-lift cam profiles. The chromoly construction provides superior strength-to-weight characteristics compared to standard steel, reducing parasitic inertia while maintaining durability through repeated thermal cycling. The 0.080-inch wall thickness is optimized for magnum applications where higher spring pressures and extended rpm ranges demand enhanced wall integrity to prevent buckling or failure. COMP CAMS' magnum-series design ensures concentricity and straightness tolerances tight enough for modern hydraulic and solid lifter conversions.

This pushrod fits small block Chevy and compatible GM V6 platforms where 7.900-inch length is the correct measurement between lifter bore center and rocker arm pivot point. Accurate length selection is non-negotiable—incorrect pushrod length causes valve overlap issues, variable valve lash, and accelerated wear on rocker arms and valve stems. Technicians and engine builders should verify cam profile, lifter type, and rocker arm geometry before ordering. Sold individually, allowing builders to replace worn or damaged rods in complete sets, or to upgrade aging pushrods during a valve train refresh. Ideal for restorations, performance street engines, and competition builds where reliability and consistent valve actuation are paramount.
