Eagle Mitsubishi 4B11T 3.700in Billet Crank 5.659in H-Beam -12cc 86.5mm Pistons Rotating Assembly

If you're building a high-performance Mitsubishi 4B11T engine, especially one that will see track time or handle forced induction like turbocharging or nitrous, a strong rotating assembly is the heart of the operation. This Eagle competition rotating assembly is built to handle the stresses of racing, giving you a solid foundation for serious power.

This assembly starts with a 3.700-inch billet 4340 steel crankshaft, which is a strong material choice for handling high RPMs and significant cylinder pressures. It's paired with 5.659-inch H-beam connecting rods, known for their robust design and ability to withstand heavy loads. These rods come with 3/8-inch ARP 2000 bolts, a popular choice for their strength and reliability in performance applications. The pistons are forged 2618 aluminum with an inverted dome design, featuring a -12cc dish and a bore size of 86.5mm, ready for your custom ring gap. They include plasma-moly file-fit rings, which allow for precise gapping to match your engine's specific needs and boost levels. To top it off, the assembly includes King XP rod and main bearings, offering excellent durability and performance for demanding conditions.

This is a complete rotating assembly designed for competition use. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to ensure the longevity of your new engine build.
