3/8 .135 Wall Moly Pushrod - 9.100 Long

The 3/8 .135 Wall Moly Pushrod – 9.100 Long from Manley represents a precision-engineered component designed for high-performance engine builds where reliability and longevity are non-negotiable. Pushrods form the critical mechanical link between a cam follower and rocker arm in pushrod-actuated valve train systems, transmitting precise lifting motion to open and close intake and exhaust valves at exact intervals. This Manley offering is purpose-built for racers, engine builders, and enthusiasts running serious naturally aspirated or forced-induction applications where stock components cannot withstand sustained high RPM loads and aggressive valve timing.

Constructed from molybdenum steel alloy, this pushrod features a 3/8-inch diameter with a .135-inch wall thickness—a specification that balances structural rigidity with minimal reciprocating mass. The moly composition resists permanent deformation under extreme valve spring pressures and thermal cycling, while the wall thickness prevents flex and ensures consistent valve event timing across the entire RPM band. At 9.100 inches in length, this pushrod suits mid-length to long-block applications common in V8 and larger displacement engines, accommodating various deck heights and rocker arm geometries. The precision-wound construction eliminates taper and runout, critical for maintaining parallel valve opening and preventing accelerated wear on both ends of the rod.

Engine builders and performance shops specify Manley pushrods when upgrading cylinder heads, installing aggressive cam profiles, or increasing valve spring pressures beyond original equipment tolerances. These components are essential when converting carbureted engines to EFI, installing solid roller cams, or building race-ready engines targeting 7,000+ RPM sustained operation. Proper installation requires checking pushrod length against the specific rocker arm and lifter configuration in your engine—incorrect length causes valve lash variability and potential contact issues. For small-block and big-block Chevy applications, Ford Windsor and Cleveland platforms, and traditional hot rod builds, verify your existing pushrod specifications and compare against this 9.100-inch moly option to ensure perfect fit and optimal valve train geometry.
