Eagle Chrysler RB 8 Bolt 4.150in Crank 6.760in H-Beam -8cc Flat Top 4.350in Piston Rotating Assembly

This Eagle Competition Rotating Assembly gives you the core components for a serious RB engine build. Inside this package, you'll find a 4.150-inch forged 4340 crankshaft, a set of 6.760-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts, and four 4.350-inch flat-top pistons from MAHLE, designed with a -8cc dish. It also includes plasma-moly file-fit piston rings and KING XP rod and main bearings to get your engine rotating smoothly.

This assembly is specifically put together for demanding racing applications, including those using nitrous oxide or forced induction. The forged 4340 steel crankshaft and H-beam connecting rods are well-built to handle the high stresses and RPMs associated with competitive motorsport. The MAHLE pistons are forged from 4032 aluminum, a material known for its strength and thermal expansion properties, making them a solid choice for high-performance engines. The included file-fit rings allow for precise gap setting to optimize compression and oil control for your specific build, and the KING XP bearings are designed for high-load performance.

When building a high-performance RB engine, having a strong rotating assembly is fundamental. This Eagle kit bundles together key components that are engineered to work together, saving you time and ensuring a solid foundation for your project. 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.
