Eagle Chevy 350 1 Pc Rear Seal 4.03in Bore 3.75in Stroke + 0.030in Rotating Assembly Kit 5140 Steel

This Eagle Street & Strip Rotating Assembly kit gives you the core components to rebuild or upgrade your Chevy 350 engine. Inside this kit, you'll find a 3.750-inch cast crankshaft, 5.700-inch I-beam connecting rods with 3/8-inch ARP 8740 bolts, hypereutectic KB pistons designed for a 4.030-inch bore with a -7cc flat top dish, standard gap plasma-moly piston rings, and King rod and main bearings. This assembly is specifically put together for pump gas, naturally aspirated street applications.

The components in this kit are well-built for reliable performance on the street. The cast crankshaft is a solid choice for many street builds, and the I-beam connecting rods are strong, especially when paired with the included ARP bolts. The hypereutectic pistons offer a good balance of strength and weight for everyday driving. This kit is designed to work with a 1-piece rear main seal configuration common in many Chevy 350 engines, and the pistons are sized at 4.030 inches, which is 0.030 inches over the standard bore size.

When you're putting together a street-driven 350, having a balanced rotating assembly is key to smooth operation and longevity. This kit simplifies the process by providing matched components. 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.
