About this part

Product Details

If you're building a high-performance Chevy LS2 or LS3 engine, especially one intended for racing, nitrous, or forced induction, a strong rotating assembly is the heart of your build. This Eagle Competition Rotating Assembly is designed to handle the stresses of serious performance applications. It starts with a 3.900-inch stroke crankshaft, which, when paired with the included 4.065-inch bore pistons, increases your engine's displacement, giving you more power potential.

The H-beam connecting rods are a popular choice for performance builds because they offer a robust design that can withstand higher cylinder pressures and RPMs compared to I-beam rods. These rods measure 6.125 inches in length, a common specification for LS engines that balances stroke and rod ratio for good performance characteristics. The assembly also includes a 24-tooth reluctor wheel, which is standard for most LS2 and LS3 applications, ensuring compatibility with your engine's computer system. This is a well-built package intended to be the foundation for a powerful engine.

When assembling an engine of this caliber, attention to detail is crucial. Ensure all components are clean, properly balanced, and lubricated according to the manufacturer's specifications. This rotating assembly is a significant investment in your engine's performance and durability, so taking the time for a meticulous build process will pay dividends on the street or track. Please note that this assembly is not CARB approved and cannot be shipped to California.
