The billet 4340 steel crankshaft is a strong choice for demanding applications, offering improved durability over cast cranks. The H-beam connecting rods are known for their robust design, capable of handling higher horsepower and stress, especially when paired with ARP 2000 bolts, which are a significant upgrade for ensuring rod security under load. The CP forged pistons are designed for performance, with the inverted dome helping to manage compression ratios and combustion chamber shape, while the file-fit rings allow for precise gap setting to optimize performance and sealing in your specific engine build. King XP bearings are chosen for their ability to maintain oil film strength under high loads and RPMs.

This assembly is intended for racing use, including applications with nitrous oxide or forced induction. It's important to note that this part is not CARB approved and cannot be shipped to California. Proper installation and tuning are critical for achieving the intended performance and longevity from this high-performance rotating assembly.
