Performance Construction:

Manley’s Lightweight Pro Series I-Beam is a fully machined forged 4340 rod aimed at performance builds where rod mass is part of the rotating-assembly plan. The profile is developed within a named weight class rather than treated as a generic I-Beam. Shot peening after machining and individual magnetic-particle inspection complement the precise dimensions and supplied ARP hardware.

For a Small Block Chevrolet build, rod length and crank journal size are defining parts of the rotating assembly. This configuration brings those dimensions together with its stated wrist-pin size, making the set a clear choice for an engine combination designed around the listed length and journal arrangement.

The 0.9281 in. pin-end bore and 2.125 in. big-end housing bore describe the two rod ends, while the 5.850 in. center-to-center measurement defines rod length. The crankshaft journal configuration is 2.000 in., paired with the housing bore specified below. Average rod weight is approximately 615 g per rod, giving this exact MPN a useful weight reference alongside its dimensions. The pin end measures 0.980 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.
