About this part

Product Details

This Eagle Pro Street rotating assembly gives you the core components to rebuild or upgrade your Chevy LS2 engine. You get a 4.000-inch forged 4140 crankshaft, a 24-tooth reluctor wheel, 6.125-inch 4340 I-beam connecting rods with 7/16-inch ARP 8740 bolts, and forged 4032 DSS pistons with an inverted dome design. It also includes plasma-moly file-fit piston rings and King XP rod and main bearings to get you started.

This assembly is built for naturally-aspirated racing applications, meaning it's designed to handle the demands of high-RPM operation without forced induction. The forged 4140 crankshaft and 4340 I-beam rods are strong choices for performance builds, offering improved durability over cast components. The 4.030-inch pistons are forged from 4032 aluminum, which offers good thermal expansion properties for a tighter piston-to-wall clearance. The included ARP bolts are a well-known name in high-strength fasteners, ensuring your connecting rods stay securely attached under stress. The plasma-moly file-fit rings allow for precise gapping to match your specific cylinder wall condition and desired performance level.

This rotating assembly is a solid foundation for a performance LS2 build. Keep in mind 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 torque specifications, especially when dealing with critical components like connecting rod bolts and main bearing caps.
