Eagle Subaru Ej25 3.110in Billet Crank 5.137in H-Beam -4.5cc Flat Top 100mm Piston Rotating Assembly

Eagle is well-known for building robust engine components, and this competition rotating assembly for the Subaru EJ25 is a prime example of their commitment to performance. If you're building an engine for serious racing, especially with nitrous or forced induction, this assembly is designed to handle the extra stress and power demands. It's a complete package that gives you the core rotating parts needed to rebuild or significantly upgrade your EJ25 engine.

At the heart of this assembly is a 3.110-inch billet 4340 crankshaft, chosen for its strength and durability under high loads. Paired with it are 5.137-inch H-beam connecting rods, which are a popular choice for their balance of strength and weight, especially when fitted with the included 3/8-inch ARP 2000 bolts. These rods are designed to withstand the intense forces generated during high-performance operation. The pistons are forged from 2618 aluminum, featuring a -4.5cc flat top design and a 100mm bore, making them suitable for various compression ratio targets. They come with plasma-moly file-fit rings, allowing for precise gap setting to optimize sealing and performance. To ensure smooth operation and longevity, the assembly includes King XP rod and main bearings, known for their reliable performance in demanding applications.

This rotating assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. It's a substantial upgrade for anyone looking to push the limits of their EJ25 engine in a racing environment. Ensure you have the necessary supporting components and expertise for installation, as this is a critical engine rebuild part.
