Performance Construction:

H-Tuff adds material at critical sections of the H-Beam and uses a reinforced, ribbed pin-end surround. That design is intended for demanding performance combinations, including engines using boost and other power adders. The forged 4340 construction, shot-peened finish and ARP 2000 cap screws make this a focused step up within Manley’s H-Beam range.

This Gen III HEMI stroker configuration uses a 6.125 in. rod and a 2.000 in. Small Block Chevrolet-style crank journal. The 2.125 in. housing bore and stated pin dimensions are central to the combination. It is a purpose-specific stroker rod with the application and geometry identified together. The single-piece quantity is useful when buying an individual rod in this specific Manley family.

The 0.9281 in. pin-end bore and 2.125 in. big-end housing bore describe the two rod ends, while the 6.125 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 665 g per rod, giving this exact MPN a useful weight reference alongside its dimensions. The pin end measures 0.930 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.
