About this part

Product Details

If you're building a high-performance Chevy LS3 engine for serious racing, especially with nitrous or forced induction, a strong rotating assembly is the heart of the operation. This Eagle Competition Rotating Assembly is built to handle the extreme demands of competition. It starts with a 4.000-inch forged 4340 steel crankshaft, a solid foundation for any powerful LS3 build. The 58-tooth reluctor wheel is standard for many LS3 applications, ensuring proper sensor readings.

Complementing the crankshaft are 6.125-inch H-beam connecting rods. These rods are well-built and secured with 7/16-inch ARP 8740 bolts, known for their strength and reliability under high stress. The pistons are forged 4032 DSS units, featuring an inverted dome design with a -29cc volume, which is crucial for achieving the desired compression ratio with your chosen cylinder heads. They come with plasma-moly file-fit rings, allowing for precise gap setting to match your engine's bore and intended use, which is important for sealing and oil control. King XP rod and main bearings are included, offering robust protection for the rotating assembly's critical journals.

This assembly is designed for the rigors of racing, including applications using nitrous oxide or turbochargers. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and balancing procedures, as rotating assemblies often require balancing to the specific vehicle and application.
