This Manley rotating assembly includes a 4340 forged steel crankshaft, 4340 forged steel H-beam connecting rods with 7/16? ARP 8740 cap screws, and 2618 forged aluminum Platinum Series pistons with Premium Chrome Moly wrist pins.

The crankshaft and connecting rods are forged from 4340 steel, a strong material known for its durability under high stress, making it ideal for performance applications. The H-beam design of the connecting rods further contributes to their strength and ability to handle significant loads. The pistons are crafted from 2618 forged aluminum, a popular choice for high-performance engines due to its excellent strength-to-weight ratio and thermal expansion properties. These pistons are paired with Premium Chrome Moly wrist pins for reliable operation.

This assembly is rated for a horsepower range of 900 HP when using the standard ARP 8740 cap screws. If you plan to push your engine harder, you can opt for ARP 2000 series cap screws, which can support up to 1,500 HP. Please note that this assembly is not CARB approved and cannot be shipped to California. It is always recommended to consult with your engine builder to ensure this rotating assembly meets the specific requirements of your build.
