About this part

Product Details

If you're building a high-performance Chevy LS1 engine for serious racing, a strong rotating assembly is the heart of your build. This Eagle Competition Rotating Assembly is designed to handle the demands of competition, whether you're running nitrous or forced induction. It includes a forged 4340 steel crankshaft with a 4.000-inch stroke, a 24-tooth reluctor for crank trigger systems, and 6.125-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts. This combination is built for durability under extreme stress.

The pistons in this assembly are forged 4032 DSS flat-tops with a -5cc dish, giving you a specific compression ratio when paired with your cylinder heads. They come with plasma-moly file-fit rings, which allow for precise gap setting to match your engine's bore and intended use. King XP rod and main bearings are included to ensure smooth rotation and proper oil clearance for the crankshaft and connecting rods. This assembly is a well-built foundation for an LS1 engine aiming for significant power output and reliability in racing environments.

This rotating assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. Ensure you have the necessary tools and knowledge for proper engine assembly, or consult a professional mechanic. This kit provides the core rotating components needed to build a powerful LS1 engine.
