Eagle Chrysler 426 Hemi 3.750in Stroke H-Beam 6.860in Pistons 4.280in Bore Rotating Assembly

This Eagle Competition Rotating Assembly is built for serious performance, especially if you're pushing your Chrysler 426 Hemi with nitrous or forced induction. What you get in this kit is a complete package designed to handle the demands of racing. It includes a forged 4340 steel crankshaft with a 3.750-inch stroke and an 8-bolt rear flange, ready for your flywheel. Paired with that are strong 4340 H-beam connecting rods, measuring 6.860 inches long, and they come equipped with 7/16-inch ARP 8740 rod bolts for a secure connection under high stress.

The assembly also features forged 4340 Diamond pistons designed for an 85cc dome and a 4.280-inch bore. These pistons are fitted with plasma-moly file-fit rings – 1/16 inch for the top and second rings, and a 3/16 inch oil ring – which help ensure a good seal and efficient combustion. To top it all off, the kit includes King XP main and rod bearings, known for their durability and performance in high-stress applications. This is a well-built rotating assembly aimed at giving your 426 Hemi the foundation it needs for competitive use.

Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's a robust option for builders focused on maximum output and reliability in racing environments.
