About this part

Product Details

When you're building a serious LS3 engine, starting with a well-built rotating assembly is key. This Eagle Competition Rotating Assembly gives you the core components you need to get your engine project off the ground. It includes a forged 4.000-inch crankshaft, 6.125-inch H-beam connecting rods with 7/16-inch ARP 8740 bolts, and -25cc inverted dome pistons with a 4.065-inch bore. This assembly is designed to handle the demands of racing, including nitrous and forced induction applications, and fits a wide range of GM vehicles like the Chevrolet Camaro, Corvette, and Cadillac CTS.

The forged 4340 steel crankshaft is built for strength, and the 6.125-inch H-beam rods with ARP bolts offer a solid connection between the crank and pistons. The included Mahle 2618 forged pistons are designed with a -25cc inverted dome to achieve a specific compression ratio, and they come with plasma-moly file-fit rings, meaning you can gap them precisely for your build. King XP rod and main bearings are also part of this package, providing reliable lubrication and wear protection for these critical rotating components.

This is a comprehensive package for anyone looking to build a high-performance LS3 engine. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and tuning procedures to ensure optimal performance and longevity.
