At the heart of this assembly is a 4.170-inch forged 4340 steel crankshaft, chosen for its strength and durability under high stress. It features 2.750-inch main journals. Paired with the crank are 6.250-inch I-beam connecting rods, also made from strong 4340 steel, and they come equipped with 7/16-inch ARP 8740 bolts, known for their reliability in performance applications. The pistons are forged 4032 aluminum from Mahle, a flat-top design with a -6cc dish, measuring 4.040 inches in diameter. This assembly also includes plasma-moly file-fit piston rings, which allow for precise gap setting to match your specific engine build, and King XP series rod and main bearings for smooth operation and excellent wear resistance.

This rotating assembly is a significant step up for a performance build. Remember, this assembly is not CARB approved and cannot be shipped to California. It's always a good idea to consult your engine builder or refer to the manufacturer's installation instructions for specific assembly details and torque specifications.
