Eagle Chevy 454 4.000in Crank 6.135in H-Beam 14cc Closed Chamber 4.310in Pistons Rotating Assembly

Eagle is well-known for building robust engine components, and this rotating assembly for the Chevy 454 is a prime example of their commitment to performance. If you're building a serious engine for racing, especially one that will see nitrous or forced induction, this assembly is designed to handle the extra stress. It includes everything you need to get the bottom end of your 454 ready for high-output duty.

At the heart of this assembly is a 4.000-inch forged 4340 steel crankshaft, chosen for its strength and durability under extreme loads. Paired with this are 6.135-inch H-beam connecting rods, also forged from 4340 steel, and secured with 7/16-inch ARP 8740 bolts. The pistons are forged 4032 aluminum from SRP, featuring a 14cc closed chamber dome design and a 4.310-inch bore size. These pistons are designed to work with the included plasma-moly file-fit rings, allowing for precise gap setting to match your specific engine build. To ensure smooth operation and proper lubrication, the assembly comes complete with King XP series rod and main bearings.

This is a competition-level rotating assembly, meaning it's built for demanding applications where reliability and strength are paramount. Please note that this assembly is not CARB approved and cannot be shipped to California. It's important to consult your engine builder or refer to manufacturer instructions for proper installation and tuning, especially when dealing with nitrous or forced induction setups.
