Eagle Subaru Ej25 3.268in Billet Crank 5.137in H-Beam -22.1cc 100mm 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-horsepower EJ25 for track use, drag racing, or any form of competition, this assembly is designed to handle the stress. It includes everything you need to get your bottom end rebuilt with robust parts that can take a beating.

At the heart of this assembly is a 3.268-inch billet 4340 steel crankshaft, chosen for its strength and durability under extreme loads. Paired with this are 5.137-inch H-beam connecting rods, which are a popular choice for their solid construction and ability to withstand high RPMs and significant cylinder pressures. These rods come equipped with 3/8-inch ARP 2000 bolts, known for their reliability and clamping force, ensuring the rods stay securely connected to the crankshaft. The pistons are forged 2618 aluminum from CP, featuring an inverted dome design with a -22.1cc volume to achieve a specific compression ratio when paired with the correct cylinder heads and deck height. These pistons are designed for a 100mm bore and come with plasma-moly file-fit rings, allowing for precise ring gap adjustment during installation. To complete the package, King XP rod and main bearings are included, offering excellent wear resistance and performance in demanding conditions.

This is a comprehensive rotating assembly built for serious performance. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer installation instructions for proper assembly and break-in procedures to ensure the longevity of your build.
