Eagle Mitsubishi 4G63 93-97 3.700in Crank 5.900in H-Beam -14cc 85.5mm Pistons Rotating Assembly

If you're rebuilding the engine in your 1993-1997 Mitsubishi 4G63, this rotating assembly from Eagle is a solid choice for serious performance. It bundles together the core components that make up the heart of your engine's power delivery: the crankshaft, connecting rods, pistons, rings, and bearings. This assembly is built to handle the demands of racing, including applications using nitrous oxide or forced induction like turbochargers and superchargers.

At the center of this assembly is a 3.700-inch forged 4340 steel crankshaft, chosen for its strength and durability under high stress. Paired with it are 5.900-inch H-beam connecting rods, known for their robust design, which come equipped with 3/8-inch ARP 2000 bolts for secure attachment. The pistons are forged 2618 aluminum from Mahle, featuring an inverted dome design with a -14cc volume and a bore size of 85.5mm, which helps achieve a specific compression ratio when combined with the rest of the components. You'll also find plasma-moly file-fit piston rings, allowing for precise gap adjustment during installation, and King XP series rod and main bearings, selected for their performance and reliability.

This rotating assembly is designed for builds where reliability and performance are paramount. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions and consult with a professional engine builder to ensure proper assembly and tuning for your specific application.
