Eagle is well-known for building strong engine components, and this Competition Rotating Assembly Kit is a prime example of their commitment to performance. If you're looking to build a powerful LS-series engine for your Chevrolet or Pontiac, this kit is designed to handle the demands of racing, including nitrous and forced-induction setups. It's engineered to create a 403 or 408 cubic inch displacement, depending on your specific build, with a 4.005-inch bore size.

Inside this kit, you'll find a forged 4340 steel crankshaft with a 4.000-inch stroke and a 58-tooth reluctor wheel for electronic timing. The 6.125-inch H-beam connecting rods are made from robust 4340 steel and secured with 7/16-inch ARP 8740 bolts, ensuring they can withstand high stress. Forged 4032 aluminum pistons feature a -12cc inverted dome design and are paired with plasma-moly file-fit piston rings, which help with sealing and oil control. To complete the assembly, King XP series rod and main bearings are included, offering excellent durability and performance under load.

This rotating assembly is a substantial upgrade for your LS-series engine and is suitable for a wide range of vehicles, including models like the Cadillac CTS, Chevrolet Camaro, and Pontiac Firebird. It's important to note that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and tuning.
