Eagle Chevy LS1 4.000in Crank 58 Tth Reluctor 6.125in H-Beam -5cc 3.913in Pistons Rotating Assembly

If you're building a high-performance Chevy LS1 engine for racing, especially with nitrous or forced induction, a robust rotating assembly is key. This Eagle Competition Rotating Assembly is designed to handle the extreme demands of competition. It starts with a 4.000-inch forged 4340 steel crankshaft, a strong foundation for significant power. The assembly includes 6.125-inch H-beam connecting rods, known for their strength and reliability under stress, secured with 7/16-inch ARP 8740 bolts. These rods are paired with forged 4032 DSS pistons that feature a -5cc flat top design and a 3.913-inch bore, ready for your chosen ring set.

This assembly is specifically configured for a 58-tooth reluctor wheel, common in many LS1 applications. It also comes complete with plasma-moly file-fit rings, allowing for precise gap setting during installation to optimize performance and sealing. For the bottom end, King XP rod and main bearings are included, offering excellent durability and low friction for smooth operation. This is a well-built package intended for serious engine builds where reliability and power output are paramount.

When assembling this rotating group, pay close attention to the file-fit rings to ensure they are gapped correctly for your specific application and intended power adder. Proper balancing of the entire rotating assembly by a professional machine shop is also highly recommended to ensure engine longevity and smooth operation at high RPMs. Please note that this assembly is not CARB approved and cannot be shipped to California.
