NotesAlloy is not stated on this listing; CP-Carrillo’s Pro-H line is a forged steel H-beam and the bolt size is the part of the specification that matters here. The factory rotating assembly is already forged, so this is not a cast-to-forged upgrade — it is a response to the 997.2 rod being reported as measurably weaker than the 997.1 item it replaced.
