Eagle Subaru Ej25 3.110in Billet Crank 5.137in H-Beam -15.5cc 99.5mm Pistons Rotating Assembly

Eagle has been a well-known name in performance engine components for a long time, and this rotating assembly for the Subaru EJ25 is built for serious work. If you're rebuilding your EJ25 for racing, especially with forced induction or nitrous, this is a solid foundation to build upon. It's designed to handle the extra stress these setups put on internal engine parts.

At the heart of this assembly is a 3.110-inch billet 4340 crankshaft, which is a strong material chosen for its durability under high loads. Paired with this are 5.137-inch H-beam connecting rods, known for their robust design, secured with 3/8-inch ARP 2000 bolts. The pistons are forged 2618 aluminum from Diamond, featuring an inverted dome design with a -15.5cc volume and a 99.5mm bore size, which is a common size for EJ25 builds looking for a bit more displacement. This assembly also comes with plasma-moly file-fit piston rings and King XP rod and main bearings, ensuring smooth operation and longevity for the critical bearing surfaces.

When putting this assembly into your EJ25, remember that it's intended for competition use and is not CARB approved, meaning it cannot be shipped to California. You'll want to consult detailed engine building guides for the proper installation procedures, especially regarding ring gap setting and bearing clearances, to ensure optimal performance and durability for your build.
