Eagle Chrysler RB 4.250in Crank 7.100in H-Beam -8cc Flat Top 4.350in Pistons Rotating Assembly

When you're building a serious performance engine for your Chrysler RB, starting with a solid rotating assembly is key. This Eagle Competition Rotating Assembly gives you the core components you need to build a strong foundation. You get a forged 4340 crankshaft with a 4.250-inch stroke, 7.100-inch H-beam connecting rods, and a set of Mahle -8cc flat top pistons designed for a 4.350-inch bore. This assembly is built to handle the demands of racing, including the stress from nitrous and forced induction setups.

Eagle has put together a well-built package here. The 4340 forged steel crankshaft is known for its strength and durability under high loads. The H-beam connecting rods are also forged, and they come with 7/16-inch ARP 8740 bolts, which are a strong choice for high-stress applications. The Mahle pistons are forged from 4032 aluminum, a material that balances strength with thermal expansion properties, and they feature a flat top design with a -8cc dish, which is important for setting your compression ratio. This assembly also includes plasma-moly file-fit piston rings, which allow for precise gap setting, and King XP rod and main bearings to ensure smooth operation and proper oil clearance.

This rotating assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. It's a comprehensive package designed to get your high-performance RB engine build off to a strong start, providing the critical internal strength needed for demanding applications.
