The Manley Rotating Assembly is a complete, matched rotating system engineered to deliver strength, balance, and consistent performance in high‑demand engines. It combines precision‑forged crankshaft technology with 4340 forged H‑beam connecting rods secured by 7/16 ARP 8740 or optional ARP 2000 cap screws, and 2618 forged aluminum Platinum Series pistons with chrome‑moly wrist pins. Tight tolerances and careful material selection improve load handling and reduce friction for reliable operation at elevated RPM.
