Eagle Chrysler RB Balanced Competition Rotating Assembly Kit

This is the Eagle Chrysler RB Balanced Competition Rotating Assembly Kit, built for serious performance applications. If you're putting together a high-horsepower engine for racing, especially with forced induction or nitrous, this kit is designed to handle the stress. It centers around a robust 4.150-inch forged 4340 crankshaft, which is the backbone for handling increased cylinder pressures and RPMs. The kit is balanced from the factory, saving you a significant step and ensuring your engine runs smoothly at high speeds.

You'll find 6.760-inch H-beam connecting rods included, made from strong 4340 forged steel and secured with 7/16-inch ARP 8740 bolts. These rods are known for their durability under extreme loads. The pistons are 4.375-inch forged 2618 JE units with an inverted dome design, featuring a -29cc dish. This specific piston design is crucial for achieving the desired compression ratio with your RB engine build, especially when paired with specific cylinder heads. They come with plasma-moly file-fit rings, which offer good sealing and wear characteristics for performance engines.

To complete the assembly, King XP rod and main bearings are included. These bearings are well-regarded for their ability to maintain oil film strength under high loads and temperatures, which is critical for engine longevity in racing conditions. Please note that this kit is not CARB approved and cannot be shipped to California. It's a comprehensive package for anyone serious about building a powerful Chrysler RB engine.
