Product Details
This Manley rotating assembly starts with a lightweight 4340 forged steel crankshaft, designed for durability under high stress. It's paired with 4340 forged steel H-beam connecting rods, which come standard with 7/16? ARP 8740 cap screws. If your build demands even more, there's an option for ARP 2000 cap screws, which significantly increases the rod's strength for extreme applications.
The pistons are Manley's Platinum Series, made from 2618 forged aluminum and include premium chrome moly wrist pins. This combination is engineered for performance and longevity. With the standard ARP 8740 cap screws, this assembly is rated for up to 750 horsepower. Opting for the ARP 2000 cap screws raises that capability to an impressive 1,500 horsepower, making this a solid choice for serious engine builds.
Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
