Pushrod - 5/16 .080 8.075 Long

The Pushrod - 5/16 .080 8.075 Long is a precision-engineered valve train component designed for high-performance engine builds and street/strip applications where reliability and consistent valve actuation matter. As an experienced mechanic, you know that pushrods are the critical link between your cam and rocker arms—they translate camshaft motion into valve lift and timing, and any variation in length, diameter, or wall thickness directly affects engine geometry and performance. This chromoly pushrod is manufactured to exact tolerances and engineered for engines where stock components no longer suffice or where custom displacement or cam timing demands a precision fit.

Built from chromoly alloy, this 8.075-inch pushrod features a 5/16-inch diameter with 0.080-inch wall thickness—specs that balance strength-to-weight ratio and flex characteristics for sustained RPM ranges. The ball ends on both ends ensure proper seating in cup-style rocker arms and lifter sockets, eliminating binding and reducing wear on valve train surfaces. Chromoly construction provides superior fatigue resistance compared to standard steel, critical when you're running aggressive cam profiles, high valve spring pressures, or extended rev limits. The 0.14-pound weight keeps rotating mass minimal, reducing inertia losses and stress on cam lobes and lifter components over extended operation.

This pushrod suits builders and enthusiasts working on small-block Chevrolet, Ford Windsor, and similar platforms where 5/16-inch pushrods are standard or required by custom builds. Whether you're restoring an engine with worn stock pushrods, assembling a stroker, or upgrading to a high-lift cam, verifying the exact length (8.075 inches) against your rocker geometry is essential—improper length causes valve bind, rocker arm angle issues, and catastrophic valve train failure. Installation requires careful measurement from lifter seat to rocker arm cup, and many builders verify length with a dial indicator after assembly to confirm zero lash at TDC. Keep a spare on hand for diagnostics or quick swaps during tune-ups.
