Performance Construction:

Manley’s H-Beam construction brings forged 4340 steel and precision-finished rod geometry together in a practical performance-engine upgrade. The manufacturing process includes heat treatment, stress relief, shot peening and magnetic-particle inspection. Attention to the housing finish, threads, bend and twist gives this series the machining detail expected in a purpose-built rotating assembly.

This Gen III HEMI family is built around a 6.240 in. stock-length rod. Manley offers distinct small-end configurations within the range, so this MPN’s listed wrist-pin diameter and pin-end bore identify the version being supplied. The housing bore and journal configuration complete the dimensional package.

The 0.9457 in. pin-end bore and 2.252 in. big-end housing bore describe the two rod ends, while the 6.240 in. center-to-center measurement defines rod length. The crankshaft journal configuration is 2.126 in., paired with the housing bore specified below. Average rod weight is approximately 675 g per rod, giving this exact MPN a useful weight reference alongside its dimensions. The pin end measures 1.000 in. wide.

The supplied 7/16 in. ARP 2000 cap screws are part of this rod’s specification. This ARP 2000 version brings the stated fastener grade together with the 4340 steel H-Beam profile, pairing the documented fastener package with the forged rod construction.
