Performance Construction:

This Pro Series variant is cataloged by Manley for NHRA Super Stock applications. It combines a fully machined 4340 I-Beam with the specified journal arrangement and a selectable pin-bore range. Those details distinguish it from a general-purpose rod set: the stock-length geometry, listed weight and class-specific configuration are central to the product’s purpose.

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 0.8761–0.9281 in. pin-end bore and 2.125 in. big-end housing bore describe the two rod ends, while the 5.700 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 560 g per rod, giving this exact MPN a useful weight reference alongside its dimensions. The pin end measures 1.000 in. wide.

The supplied 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.
