Eagle Ford FE 4.125in Crank 6.700in I-Beam Rods Forged 4032 -14cc 4.165in Pistons Rotating Assembly

This Eagle Street & Strip rotating assembly gives you the core components to rebuild or upgrade the heart of your Ford FE engine. You get a 4.125-inch cast crankshaft, 6.700-inch I-beam connecting rods fitted with 7/16-inch ARP 8740 bolts, and a set of forged 4032 Diamond pistons. These pistons feature an inverted dome design with a -14cc dish and are sized for a 4.165-inch bore. The assembly also includes plasma-moly file-fit piston rings and King rod and main bearings, providing a solid foundation for your build.

This assembly is designed for street vehicles running on pump gas and intended for naturally aspirated applications. The 4032 aluminum alloy used for the pistons offers good thermal expansion characteristics, making them suitable for street use. The I-beam connecting rods are well-built for this type of application, and the inclusion of ARP 8740 bolts means you have strong fasteners for the rods. The cast crankshaft is a durable choice for street performance, and the King bearings are known for their reliability. The plasma-moly rings are file-fit, allowing for precise gap setting during assembly, which is crucial for proper engine sealing and performance.

When assembling this rotating assembly, pay close attention to the piston ring gap setting, as the file-fit rings require careful measurement and adjustment based on your specific cylinder bore and intended use. This kit is intended for naturally aspirated, pump gas street applications and is not CARB approved, meaning it cannot be shipped to California. Ensure you consult your engine builder or service manual for detailed assembly procedures and specifications.
