Eagle Subaru Ej25 3.268in Billet Crank 5.137in H-Beam -22.1cc 100.5mm Pistons Rotating Assembly

Eagle is well-known for making strong internal engine components, and this rotating assembly for the Subaru EJ25 is a prime example of their commitment to performance. If you're building a high-performance EJ25 engine, especially for racing applications like drag racing or time attack, this assembly is designed to handle the stress. It includes everything you need to get your short block built with robust internals.

At the heart of this assembly is a 3.268-inch billet 4340 steel crankshaft. Billet steel cranks are significantly stronger than cast or even forged cranks, making them ideal for engines that will see high RPMs and significant power adders like turbochargers or nitrous oxide. Paired with the crank are 5.137-inch H-beam connecting rods, which are also known for their strength and reliability under load. These rods come with 3/8-inch ARP 2000 bolts, a popular choice for their durability and ability to withstand high clamping forces. The pistons are forged 2618 aluminum from CP, a respected name in piston manufacturing. These are inverted dome pistons with a -22.1cc volume, designed to work with the crank and rod combination to achieve a specific compression ratio. The assembly also includes plasma-moly file-fit piston rings, which allow for precise gap setting to match your engine's bore and intended use, and King XP rod and main bearings, 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 package for anyone serious about building a powerful and reliable Subaru EJ25 engine for demanding applications.
