Eagle Chrysler RB 4.150in Crank 6.760in H-Beam -8cc Flat Top 4.350in Pistons Balanced Assembly

What you get in this balanced rotating assembly is a complete package ready to be installed in your Chrysler RB engine. It features a 4.150-inch forged 4340 crankshaft, paired with 6.760-inch H-beam connecting rods secured by 7/16-inch ARP 8740 bolts. The assembly also includes 4.350-inch flat-top pistons from Mahle, designed with a -8cc dish, along with plasma-moly file-fit rings and King XP rod and main bearings.

This assembly is built for serious performance, making it a solid choice for racing applications, including those using nitrous or forced induction. The forged 4340 crank and H-beam rods are known for their strength, capable of handling the stresses of high-RPM operation and increased cylinder pressures. The Mahle pistons are forged from 4032 aluminum, which offers good thermal expansion properties for a tighter piston-to-wall clearance, contributing to reduced noise and improved sealing. The included file-fit rings give you the flexibility to set your own ring gap, which is crucial for optimizing performance and sealing in modified engines. King XP bearings are specified for their robust construction and ability to maintain oil film under demanding conditions.

This balanced rotating assembly is ready for your performance build. Please note 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 optimal performance and longevity.
