Eagle Subaru Ej25 3.110in Billet Crank 5.137in H-Beam -4.5cc 99.5mm Pistons Rotating Assembly

This is a complete rotating assembly from Eagle, built for Subaru EJ25 engines. It includes a billet crankshaft, H-beam connecting rods, and pistons designed for a 99.5mm bore with a -4.5cc dish. This assembly is a solid choice if you're rebuilding the bottom end of your EJ25 and looking for a strong, well-built setup that can handle more power than stock.

The heart of this assembly is the Eagle billet crankshaft. Billet cranks are machined from a solid block of steel, making them significantly stronger and more durable than cast or forged cranks. This strength is crucial for engines that see high RPMs or are tuned for increased horsepower. The H-beam connecting rods are also well-known for their strength-to-weight ratio, making them a popular choice for performance builds. They are paired with pistons that have a -4.5cc dish, which will affect your compression ratio depending on your cylinder head volume. This assembly is designed for a 3.110-inch main journal and 5.137-inch rod length, ensuring proper fitment within the EJ25 block with the correct bearings.

When installing this rotating assembly, it's important to ensure your engine block is properly machined and cleaned. All components should be meticulously balanced as a set before installation. You'll also need to select the correct main and rod bearings, as they are not included in this assembly. Remember that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for detailed procedures and specifications.
