5/16 Moly Pushrods - 6.250 Long

The 5/16 Moly Pushrods - 6.250 Long set of 16 delivers the precision valve train control that serious engine builders and high-performance mechanics demand. Pushrods are the mechanical backbone of your valvetrain, transferring camshaft lift directly to rocker arms with zero slop or deflection. Whether you're assembling a street engine, competition build, or classic car restoration, quality pushrods are non-negotiable—poor valve actuation leads to timing misfire, loss of power, and potential catastrophic valve float at high RPM.

These chromoly pushrods feature a 5/16-inch diameter with 0.080-inch wall thickness, engineered to resist bending and maintain dimensional stability under sustained high-load conditions. The 6.250-inch length suits small-block applications across popular platforms, while swedged ends ensure positive engagement with both pushrod cups and rocker arm geometry. Chromoly construction provides superior strength-to-weight ratio compared to standard steel, reducing inertial mass while delivering the rigidity needed to prevent deflection during aggressive valve acceleration—critical for maintaining accurate cam timing and preventing rocker arm walk-out.

This complete set of 16 pushrod units is ideal for engine rebuilds, cam upgrades, or performance modifications where factory pushrods have reached service limits or cannot support elevated valve spring pressures. Verify your engine's specific 6.250-inch length requirement before installation—pushrod length is critical and directly affects rocker arm geometry and valve lash settings. Proper installation includes checking for bearing wear at the block and head surfaces, and confirming rocker arm geometry after assembly to ensure optimal valve control and longevity.
