Eagle Chrysler 400 4.150in Crank 6.760in H-Beam -8cc Flat Top 4.375in Pistons Rotating Assembly

This Eagle rotating assembly gives you a complete package for your Chrysler 400 engine build. You get a forged 4340 crankshaft with a 4.150-inch stroke, 6.760-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts, and Mahle forged 4032 flat-top pistons with a -8cc dish for a 4.375-inch bore. It also includes plasma-moly file-fit piston rings and King XP rod and main bearings to get your engine rotating smoothly.

This assembly is built for demanding use, including racing applications that might involve nitrous or forced induction. The forged 4340 steel crankshaft is a strong foundation, and the H-beam rods are well-suited for high-stress environments. The Mahle pistons are forged from 4032 aluminum, which offers good thermal expansion properties for a tighter piston-to-wall clearance. The included ARP bolts are a solid choice for connecting the rods, and the King XP bearings are designed for high-performance lubrication needs.

When putting this assembly together, remember that the piston rings are file-fit, meaning you'll need to check and adjust the end gap to match your specific cylinder bore size and intended use. This is a common practice for high-performance builds to ensure proper sealing and oil control. This assembly is not CARB approved and cannot be shipped to California.
