Eagle Chevy LS1 4.000in Crank 58 Tth Reluctor 6.125in H-Beam -5cc 3.900in Pistons Rotating Assembly

Eagle is well-known for building robust engine components, and this Competition Rotating Assembly is a prime example of their work for Chevy LS1 engines. If you're building a high-performance LS1 for racing, especially with nitrous or forced induction, this assembly is designed to handle the extra stress. It's a complete package that gives you the core rotating parts you need to get your engine build underway.

At the heart of this assembly is a 4.000-inch forged 4340 steel crankshaft, chosen for its strength and durability under demanding conditions. Paired with it are 6.125-inch H-beam connecting rods, which are also forged for maximum strength. These rods come equipped with 7/16-inch ARP 8740 bolts, a name you can trust for reliable clamping force. The pistons are forged 4032 aluminum flat tops with a -5cc dish, designed for a 3.900-inch bore and come with plasma-moly file-fit rings, allowing for precise gap setting during installation. This assembly also includes King XP rod and main bearings, known for their performance and durability.

This rotating assembly is specifically configured for a 58-tooth reluctor wheel, common in many LS1 applications. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Ensure you check all manufacturer specifications and consult with your engine builder to confirm compatibility with your specific build plans.
