About this part

Product Details

This Eagle rotating assembly gives you the core components to rebuild or upgrade your Chevy LS3 engine. You get a 4.000-inch forged 4340 crankshaft, a 58-tooth reluctor wheel for crank trigger systems, a set of 6.125-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts, and 4.065-inch SRP 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 demanding use, including racing applications that might involve nitrous or forced induction. The forged 4340 steel crankshaft is strong and durable, designed to handle increased stress. The H-beam connecting rods are also well-built for high-RPM performance, and the ARP bolts ensure a secure connection. The SRP pistons are forged from 4032 aluminum, known for its good thermal expansion properties, and feature an inverted dome to work with specific combustion chamber designs. The file-fit rings allow for precise gapping to match your engine's bore and intended use, which is crucial for optimal sealing and performance. King XP bearings are included for reliable lubrication and wear resistance.

This is a competition-level assembly, so it's important to ensure all components are installed correctly according to manufacturer specifications. Proper balancing of the rotating assembly is also critical for engine longevity and smooth operation. Please note that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified mechanic for installation and tuning advice.
