Performance Construction:

The Standard Weight Pro Series I-Beam combines a fully machined forged 4340 profile with application-specific rod geometry and ARP fasteners. Its defined weight class makes it straightforward to distinguish this set from Manley’s Lightweight and 300M alternatives. Shot peening after machining and individual magnetic-particle inspection are part of the Pro Series construction process.

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 0.9281 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. Average rod weight is approximately 700 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 I-Beam profile, pairing the documented fastener package with the forged rod construction. Manley catalogs this version with a heavier beam for forced-induction applications.
