Eagle Mitsubishi 4G63 93-97 3.937in Crank 5.900in H-Beam -19cc 85.5mm Pistons Rotating Assembly

This is the Eagle Competition Rotating Assembly, built for serious performance in your 1993-1997 Mitsubishi 4G63 engine. What you get in this package is a complete rotating assembly ready to be installed. It includes a forged 4340 crankshaft with a 3.937-inch stroke, 5.900-inch H-beam connecting rods fitted with 3/8-inch ARP 2000 bolts, and 85.5mm forged 4032 Mahle pistons featuring a -19cc inverted dome. You also get plasma-moly file-fit piston rings and King XP rod and main bearings to complete the set.

This assembly is designed for demanding use, including racing applications, and can handle the stress of nitrous and forced induction. The forged 4340 steel crankshaft is strong and durable, while the H-beam connecting rods are well-built for high RPM and significant cylinder pressures. The Mahle pistons are forged for strength and feature a specific dome volume to achieve a desired compression ratio when paired with the included components. The plasma-moly file-fit rings allow for precise gapping to match your engine's bore and intended use, ensuring optimal sealing and performance. King XP bearings are known for their robust construction and ability to handle heavy loads.

When building a high-performance engine, especially one that will see track time or forced induction, a strong rotating assembly is crucial. This Eagle kit provides the core components needed to build a robust short block. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures to ensure the longevity of your new engine components.
