Eagle Chrysler RB 505ci Balanced Rotating Assembly Kit .030in Bore

If you're building a serious performance engine for your Chrysler RB, a balanced rotating assembly is the foundation you need. This kit from Eagle takes the guesswork out of matching critical components, ensuring everything works together smoothly for maximum power and reliability, especially when you're pushing the limits with nitrous or forced induction.

Inside this kit, you'll find a forged 4340 steel crankshaft with a 4.250-inch stroke, paired with strong 7.100-inch H-beam connecting rods. These rods are secured with robust 7/16-inch ARP 8740 bolts, known for their strength under high stress. The pistons are forged 4032 aluminum flat tops from Mahle, designed with a -8cc dish to achieve a specific compression ratio when paired with the rest of the assembly. They come with plasma-moly file-fit rings, giving you control over the final piston-to-wall clearance for optimal sealing and performance. To top it off, the kit includes King XP series rod and main bearings, which offer improved durability and performance for demanding applications.

This assembly is balanced from the factory, saving you a significant step and cost in your engine build. It's important to note that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions for proper assembly and break-in procedures.
