Product Details

If you're building a high-performance Chevy LS3 engine for racing, this Eagle Competition Rotating Assembly is a solid foundation. It's designed to handle the demands of competition, whether you're running nitrous or forced induction. This assembly includes a forged 4.000-inch crankshaft, 6.125-inch H-beam connecting rods with ARP 7/16-inch bolts, and Mahle 4.070-inch pistons with a -25cc inverted dome.

The forged 4340 steel crankshaft is built for strength, and the 24-tooth reluctor wheel is standard for many LS3 applications. The H-beam rods are well-known for their durability under stress, and the Mahle pistons are forged from 4032 aluminum, a material chosen for its strength and thermal expansion properties, making them suitable for high-horsepower builds. The included King XP bearings are designed for high-load applications, offering improved oil clearance and protection. This assembly is a popular choice for LS3 builds aiming for significant power increases.

This rotating assembly fits a wide range of GM vehicles, including models like the Cadillac CTS, Chevrolet Camaro, and Pontiac GTO. 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 torque specifications to ensure optimal performance and longevity of your engine build.
