Eagle Chevy LS3 4.125in Crank 24 Tth Reluctor 6.125in H-Beam -8cc 4.070in Pistons Rotating Assembly

If you're building a high-performance Chevy LS3 engine for racing, especially with nitrous or forced induction, a strong rotating assembly is key. This Eagle Competition Rotating Assembly is built to handle the demands of serious power. It centers around a robust 4.125-inch forged 4340 crankshaft, designed for durability under extreme stress. The 24-tooth reluctor ensures compatibility with standard LS3 engine management systems.

Complementing the crankshaft are 6.125-inch H-beam connecting rods, which are known for their strength and reliability in high-RPM applications. These rods are secured with 7/16-inch ARP 8740 bolts, a popular choice for their proven performance. The assembly includes forged 4032 Mahle pistons with a -8cc flat top design and a 4.070-inch bore size, paired with plasma-moly file-fit rings for a precise seal. King XP rod and main bearings are included, offering excellent wear resistance and performance.

This rotating assembly is a well-built foundation for a powerful LS3 engine. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
