Eagle is well-known for making strong internal engine components, and this rotating assembly is a prime example of their work for the Mitsubishi 4G63 engine, specifically for 1998 and newer applications. If you're building a performance engine for racing, whether it's naturally aspirated, turbocharged, or uses nitrous, this assembly is designed to handle the extra stress.

This kit includes a 3.937-inch forged 4340 crankshaft, which is a robust choice for high-performance builds. Paired with it are 5.900-inch H-beam connecting rods, 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 maintain clamping force. The pistons are forged 2618 aluminum from Mahle, featuring an inverted dome design with a -19cc volume and a bore size of 85.5mm, which helps achieve a specific compression ratio for your build. The assembly also includes plasma-moly file-fit piston rings, allowing for precise gap setting, and King XP rod and main bearings for smooth operation and longevity.

This is a competition-level assembly intended for demanding use. Please note that this part is not CARB approved and cannot be shipped to California. It's important to consult your engine builder or refer to manufacturer specifications for proper installation and tuning to maximize the performance and lifespan of this rotating assembly.
