Eagle Subaru Ej25 3.268in Billet Crank 5.137in H-Beam -7.8cc 99.75mm Pistons Rotating Assembly

This is the Eagle Subaru EJ25 billet rotating assembly, designed for serious performance builds. It includes a 3.268-inch billet 4340 crankshaft, 5.137-inch H-beam connecting rods with 3/8-inch ARP 2000 bolts, forged 2618 CP pistons with a -7.8cc inverted dome, plasma-moly file-fit piston rings, and King XP rod and main bearings. This assembly is engineered for demanding applications like racing, including those using nitrous or forced induction.

The billet 4340 steel crankshaft is a strong foundation for high-horsepower engines, offering improved durability over cast cranks. The H-beam connecting rods are also well-built for high stress, and the inclusion of ARP 2000 bolts ensures a secure connection under extreme loads. The CP pistons are forged from 2618 aluminum, a material known for its strength and ability to handle high temperatures and pressures, and the inverted dome design helps manage compression for boosted or nitrous applications. The plasma-moly file-fit rings allow for precise gap setting, crucial for optimal sealing and performance in modified engines. King XP bearings are chosen for their robust construction and ability to handle the increased loads found in performance applications.

This rotating assembly is a comprehensive package for rebuilding or upgrading your Subaru EJ25 engine. It is important to note 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.
