About this part

Product Details

If you're building a high-performance Chevy LS7 engine for serious racing, this Eagle competition rotating assembly is a solid foundation. It's designed to handle the demands of competition, including nitrous and forced induction setups. This assembly includes a forged 4.000-inch stroke crankshaft made from 4340 steel, a 58-tooth reluctor wheel for crank trigger systems, and 6.125-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts. The pistons are forged 4032 DSS flat-tops with a -5cc dish, measuring 4.155 inches in bore size, and come with plasma-moly file-fit rings. King XP rod and main bearings are also included to ensure smooth operation and durability.

This assembly is built with robust materials to withstand the stresses of racing. The forged 4340 steel crankshaft offers excellent strength and reliability for high RPM applications. The H-beam connecting rods are a popular choice for performance builds due to their strong I-beam cross-section, and the ARP bolts ensure they stay securely fastened under extreme loads. The 4032 forged pistons are a good balance of strength and lighter weight, suitable for high-performance street and track use. The included King XP bearings are known for their performance and durability in demanding engine builds.

When assembling your LS7, ensure you follow the manufacturer's specifications for all clearances and torque values. This rotating assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. It's a critical set of components that will define the power potential and reliability of your LS7 build.
