About this part

Product Details

This Eagle rotating assembly starts with a 4.000-inch stroke forged 4340 steel crankshaft, a solid foundation for building a powerful LS3 engine. It's designed with a 24-tooth reluctor wheel, essential for proper engine management on many LS-based applications. The assembly includes 6.125-inch H-beam connecting rods, known for their strength and reliability under demanding conditions. These rods are secured with 7/16-inch ARP 8740 bolts, a popular choice for their durability and consistent clamping force.

The pistons are forged 4032 DSS flat-top units, featuring a -5cc dish to achieve a specific compression ratio when paired with the right cylinder heads. They come with plasma-moly file-fit rings, allowing for precise gap setting to optimize sealing and performance. For the bearings, Eagle has included King XP rod and main bearings, which offer improved durability and reduced friction, crucial for high-RPM operation and extended engine life. This complete package is engineered for all forms of racing, including applications using nitrous oxide or forced induction, making it a robust choice for serious engine builds.

Please note that this assembly is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning. Ensure you consult with your engine builder or refer to Eagle's technical documentation for specific installation procedures and compatibility with your chosen cylinder heads and block.
