About this part

Product Details

This Eagle Pro Street rotating assembly gives you the core components to rebuild or upgrade your Chevy LS3 engine. You get a forged 4140 crankshaft with a 3.622-inch stroke, designed for a 58-tooth reluctor wheel. It also includes 6.125-inch I-beam connecting rods made from 4340 steel, fitted with 7/16-inch ARP 8740 bolts. The assembly is completed with forged 2618 Mahle pistons featuring an inverted dome design for a -12cc volume, a 4.030-inch bore size, plasma-moly file-fit rings, and King XP rod and main bearings.

This assembly is built with strong, forged components to handle the demands of a performance street engine. The 4140 forged steel crankshaft and 4340 I-beam connecting rods are well-suited for increased power output compared to stock cast parts. The Mahle pistons are also forged, offering better resistance to detonation and heat. The inclusion of ARP bolts for the connecting rods signifies a commitment to robust assembly, ensuring the rods stay securely fastened under stress. Plasma-moly file-fit rings allow for precise piston-to-wall clearance, which is crucial for optimal sealing and performance in a performance application. King XP bearings are known for their durability and ability to maintain oil film under load.

This rotating assembly is a significant step up for an LS3 build, providing a solid foundation for increased horsepower. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer installation instructions for proper assembly and torque specifications.
