Paired with the crank are 5.700-inch long I-beam connecting rods, also made from forged 4340 steel. These rods are secured with 7/16-inch ARP 8740 bolts, known for their strength and reliability in high-performance engines. The assembly includes forged 4032 aluminum pistons with an inverted dome design, featuring a -16cc volume and a 4.165-inch bore size. These pistons are designed to work with the included plasma-moly file-fit piston rings, allowing for precise gap setting during installation. King XP rod and main bearings are also part of this comprehensive package, offering robust lubrication and wear protection for critical rotating components.

This assembly is a well-built package designed for serious performance. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures to ensure optimal performance and longevity.
