Product Details

This is the Eagle Chevy LS3 rotating assembly, a complete package designed for serious engine builds. Inside this kit, you'll find a 3.622-inch forged 4340 crankshaft, a 58-tooth reluctor wheel for crank trigger systems, and a set of 6.125-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts. It also includes forged 4032 Mahle flat-top pistons with a -4cc dish, measuring 4.070 inches in bore size, complete with plasma-moly file-fit rings, and King XP rod and main bearings to get your engine rotating smoothly.

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.
