This assembly starts with a 3.400-inch forged 4340 crankshaft, known for its strength and durability under high stress. Paired with it are 5.400-inch forged 4340 I-beam connecting rods, which are a popular choice for performance builds. These rods come equipped with 7/16-inch ARP 8740 bolts, a well-respected name in high-strength fasteners, ensuring a secure connection. The pistons are forged 4032 aluminum from MAHLE, featuring a -6cc flat top design and a 4.040-inch bore size. They come with plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. To complete the package, King XP rod and main bearings are included, offering robust lubrication and wear resistance for the critical rotating components.

This assembly is designed for performance applications and is not CARB approved, meaning it cannot be shipped to California. Ensure you have the necessary tools and expertise for proper installation, as precise balancing and assembly are crucial for engine longevity and performance.
