Eagle Chrysler RB 8 Bolt 4.150in Crank 6.760in H-Beam -8cc Flat Top 4.375in Piston Rotating Assembly

If you're building a high-performance Chrysler RB engine for serious racing, this Eagle Competition Rotating Assembly is a solid foundation. It's designed to handle the demands of applications using nitrous or forced induction, giving you the strength and reliability needed to push your engine hard. This assembly includes a forged 4340 crankshaft, H-beam connecting rods, and forged pistons, all balanced and ready for installation.

The heart of this assembly is the 4.150-inch forged 4340 steel crankshaft, known for its exceptional strength and durability under high stress. Paired with it are 6.760-inch H-beam connecting rods, which are a popular choice for racing builds due to their robust design and ability to withstand significant loads. These rods are secured with 7/16-inch ARP 8740 bolts, a name trusted in high-performance engine building for their consistent clamping force. The pistons are forged 4032 Mahle flat tops, measuring 4.375 inches in diameter with a -8cc dish, designed for optimal combustion in performance applications. They come with plasma-moly file-fit rings, allowing for precise ring gap adjustment to match your specific engine build and boost levels. To complete the rotating assembly, King XP rod and main bearings are included, offering excellent wear resistance and smooth operation.

This assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. Ensure you have the correct 8-bolt crankshaft flange configuration on your RB engine block for proper fitment. This is a critical component for anyone serious about building a powerful and reliable RB engine for the track or strip.
