Eagle Chevrolet/Pontiac LS-Series Competition Assembly 4.005in Bore 6.125in H-Beam

When you're building a serious LS-series engine for racing, especially one that will handle nitrous or forced induction, you need a rotating assembly that can take the abuse. This Eagle Competition Rotating Assembly is designed for just that. What you get in this kit is a 4.000-inch forged 4340 crankshaft, a 58-tooth reluctor wheel, 6.125-inch H-beam connecting rods, and 7/16-inch ARP 8740 bolts to hold it all together. It also includes forged 4032 Mahle pistons with an inverted dome design, measuring 4.005 inches in bore size, along with plasma-moly file-fit rings and King XP rod and main bearings.

This assembly is built with robust materials to handle the demands of competition. The forged 4340 steel crankshaft is strong and durable, while the H-beam connecting rods are a popular choice for their strength-to-weight ratio in high-performance applications. The Mahle pistons are forged from 4032 aluminum, which offers good thermal expansion characteristics for a tighter piston-to-wall clearance, and they come with plasma-moly rings that are designed to be file-fit for precise gap setting. The inclusion of ARP 8740 bolts for the connecting rods means you're getting fasteners known for their reliability under high stress.

This rotating assembly fits a wide range of Chevrolet and Pontiac LS-series engines, including popular models like the Chevrolet Corvette (1997-2010), Chevrolet Camaro (1998-2002, 2010-2013), and Pontiac GTO (2004-2006). It's important to note that this assembly is not CARB approved and cannot be shipped to California. For a competition build, ensuring all components are properly balanced and installed according to manufacturer specifications is key to achieving optimal performance and longevity.
