Eagle Chevrolet 409 Pro Street Rotating Assembly

What you get in this Eagle Pro Street Rotating Assembly is a complete package ready for a serious build. Inside this box, you'll find a 4.000-inch forged 4340 crankshaft, a set of 6.135-inch 4340 I-beam connecting rods fitted with 7/16-inch ARP 8740 bolts, and a set of forged 2618 Ross pistons. These pistons have a .365-inch dome, designed to achieve 10:1 compression with a 4.342-inch bore size, along with plasma-moly standard gap rings. To finish it off, King XP rod and main bearings are included to ensure smooth operation.

This assembly is specifically put together for naturally-aspirated racing applications. The forged 4340 steel used for both the crankshaft and connecting rods means these components are well-built to handle the stresses of high-performance engines. The ARP bolts are a strong choice for connecting rods, known for their reliability under high loads. The Ross pistons are forged from 2618 aluminum, a material chosen for its strength and ability to withstand high temperatures and pressures common in racing. The included plasma-moly rings are standard gap, which is typical for racing setups, and the King XP bearings are designed for demanding use, providing solid lubrication and wear resistance.

This rotating assembly is intended for use in Chevrolet 409 engines. Please be aware that this part is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
