This kit includes a 3.937-inch forged 4340 crankshaft, 5.900-inch H-beam connecting rods fitted with 3/8-inch ARP 2000 bolts, and 85.5mm forged 4032 Mahle pistons featuring a -19cc inverted dome.

This rotating assembly is built for demanding use, including racing applications with nitrous or forced induction. The forged 4340 steel crankshaft offers a solid foundation, while the H-beam connecting rods are known for their strength and reliability under high stress. The Mahle pistons are forged from 4032 aluminum, which is a good choice for high-performance applications due to its thermal expansion properties, and the -19cc dome helps achieve a desired compression ratio. The inclusion of ARP 2000 bolts for the connecting rods means you have strong, dependable fasteners. The plasma-moly file-fit rings allow for precise gapping to match your engine's bore and intended use, and the King XP bearings are designed for enhanced durability and performance.
This is a well-built rotating assembly intended 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.
