Eagle Chevy LS1 4.000in Crank 24 Tth Reluctor 6.125in H-Beam -29cc 3.900in Pistons Rotating Assembly

This is the Eagle Chevy LS1 rotating assembly, a well-built package designed for serious performance builds. It features a 4.000-inch forged 4340 steel crankshaft, a 24-tooth reluctor wheel for electronic timing, and 6.125-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts. The assembly includes forged 4032 DSS pistons with a -29cc inverted dome, measuring 3.900 inches in bore diameter, and plasma-moly file-fit piston rings. King XP rod and main bearings are also part of this comprehensive kit, ready to handle the demands of racing, including nitrous and forced induction applications.

When you're building a high-performance LS1 engine, the rotating assembly is the heart of it all. Eagle has put together a strong combination here using forged 4340 steel for the crankshaft, which is known for its durability under high stress. The H-beam rods are a popular choice for their strength-to-weight ratio, and the ARP bolts ensure they stay securely fastened. The pistons are forged from 4032 aluminum, a material that offers good thermal expansion properties for a tighter piston-to-wall clearance, and the inverted dome design helps manage compression ratios for boosted or nitrous applications. The plasma-moly file-fit rings give you the flexibility to achieve a precise seal in the cylinder bore, which is crucial for both power and oil control.

This assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. It's a solid foundation for an engine that needs to perform reliably under extreme conditions. Make sure to consult your engine builder or refer to the manufacturer's instructions for proper installation and balancing procedures, as rotating assemblies typically require balancing to the specific application.
