About this part

Product Details

Starting with a 3.900-inch stroke crankshaft, this Eagle rotating assembly is built for serious performance applications, especially those involving nitrous or forced induction. It's designed to handle the extra stress these power adders put on the engine's core components. The assembly includes a 58-tooth reluctor wheel, which is crucial for proper engine management and tuning on LS-based engines.

The heart of this package is the robust 6.125-inch H-beam connecting rods. These rods are well-known for their strength and ability to withstand high RPMs and significant cylinder pressures, making them a popular choice for racing. Paired with these rods are 3.810-inch pistons, completing the rotating assembly. This combination is specifically balanced to ensure smooth operation and durability under demanding conditions. Eagle has a solid reputation for building reliable engine components for performance enthusiasts.

This assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. It's a comprehensive package for anyone looking to build a high-performance LS engine for racing or extreme street applications. Ensure you have the necessary supporting components and expertise for installation, as this is a significant engine build.
