This assembly is built for performance, especially for racing applications that might involve nitrous or forced induction. The forged 4340 steel crankshaft is a strong foundation, capable of handling the stresses of high-RPM operation. The H-beam connecting rods are well-known for their strength and durability under load, and the ARP bolts ensure they stay securely fastened. Mahle pistons are a popular choice for their consistent quality and performance, and the included King XP bearings are designed for demanding use, offering excellent protection for both the crankshaft and connecting rod journals.
This rotating assembly is a significant step up for anyone rebuilding or building a high-performance LS3 engine. It's important to 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 to ensure the longevity and performance of your new engine components.
