Eagle Mitsubishi 4G63 89-92 3.937in Crank 5.900in H-Beam -19cc 86mm Pistons Rotating Assembly

If you're building a high-performance Mitsubishi 4G63 engine for racing, especially with forced induction or nitrous, this rotating assembly from Eagle is a solid choice. It's designed to handle the extra stress and power these setups demand, giving you a strong foundation for your build. This assembly includes everything you need to get your bottom end rebuilt with robust components.

At the heart of this assembly is a 3.937-inch forged 4340 crankshaft, known for its strength and durability under high loads. Paired with this are 5.900-inch H-beam connecting rods, which are a popular choice for their balance of strength and weight, secured with 3/8-inch ARP 2000 bolts. The pistons are 86mm forged 4032 MAHLE units with an inverted dome design, featuring a -19cc volume to help achieve your desired compression ratio. They come with plasma-moly file-fit rings, allowing for precise gap setting to match your engine's specific needs and operating conditions. To top it off, King XP rod and main bearings are included, offering excellent wear resistance and smooth operation for the crankshaft.

This assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. Ensure you check all manufacturer specifications and local regulations before installation.
