Eagle Chevy 454 4.250in 4140 Steel Crank 6.385in I-Beam Rods 23cc 4.280in Pistons Balanced Assembly

This Eagle rotating assembly starts with a forged 4140 steel crankshaft featuring a 4.250-inch stroke, a solid foundation for building a powerful Chevy 454 engine. It's designed for street vehicles running on pump gas and naturally aspirated setups, making it a popular choice for those looking to rebuild or upgrade their engine's core strength. The assembly is balanced from the factory, saving you a critical step and ensuring smoother operation right out of the box.

Complementing the crankshaft are 6.385-inch I-beam connecting rods made from strong 4340 steel, secured with 7/16-inch ARP 8740 bolts. These rods are built to handle the stresses of performance street driving. The kit includes forged 4032 aluminum pistons from ICON, featuring a 23cc dome volume and a 4.280-inch bore size, designed to work with the crank and rods for optimal compression. You'll also find plasma-moly file-fit piston rings and King XP rod and main bearings included, providing a well-rounded package for your engine build.

Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's a robust option for many Chevy 454 applications, but always consult with your engine builder or refer to manufacturer specifications to ensure it aligns with your specific build goals and local emissions regulations.
