Eagle Chrysler RB 8 Bolt 4.150in Crank 6.760in H-Beam -29cc 4.375in Pistons Rotating Assembly

Eagle is well-known for making strong engine components, and this rotating assembly is a prime example of their commitment to performance. If you're building a serious engine for racing, especially one that will use nitrous or forced induction, this assembly is built to handle the stress. It's a complete package designed to give you a solid foundation for a high-output powerplant.

At the heart of this assembly is a 4.150-inch forged 4340 crankshaft, chosen for its strength and durability under extreme loads. Paired with it are 6.760-inch H-beam connecting rods, also forged from 4340 steel, which are known for their robust design. These rods use 7/16-inch ARP 8740 bolts, a popular choice for their reliability in high-stress applications. The pistons are forged 2618 JE units with an inverted dome design, featuring a -29cc volume and a 4.375-inch bore size. They come with plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. To top it off, the assembly includes King XP rod and main bearings, which offer excellent wear resistance and smooth operation.
