Eagle Subaru Ej25 3.268in Billet Crank 5.137in H-Beam -17.1cc 100.5mm Pistons Rotating Assembly

Eagle is well-known for building strong engine components, and this rotating assembly for the Subaru EJ25 is a prime example of their commitment to performance. This is a complete package designed to handle the demands of serious racing, including applications using nitrous or forced induction. It’s a well-built foundation for a high-horsepower engine build.

At the heart of this assembly is a 3.268-inch billet 4340 steel crankshaft, chosen for its strength and durability under extreme stress. Paired with this are 5.137-inch H-beam connecting rods, known for their robust design and ability to withstand high RPMs and significant cylinder pressures. These rods are secured with 3/8-inch ARP 2000 bolts, a popular choice for their reliability in performance applications. The pistons are forged 2618 aluminum from CP, featuring an inverted dome design with a -17.1cc volume and a 100.5mm bore size, allowing for a specific compression ratio tailored for boosted or nitrous setups. They come with plasma-moly file-fit rings, giving you the flexibility to achieve a precise piston-to-wall clearance. To complete the assembly, King XP rod and main bearings are included, offering excellent wear resistance and performance.

This rotating assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. It’s a comprehensive kit for builders looking to maximize the performance and durability of their Subaru EJ25 engine.
