About this part

Product Details

This Eagle Competition Rotating Assembly is built for Chevy LS2 and LS3 engines, featuring a 3.800-inch stroke crankshaft, 6.125-inch H-beam connecting rods, and pistons sized for a 4.005-inch bore. This assembly is designed to handle the demands of serious racing, including applications using nitrous oxide or forced induction systems. It’s a well-built foundation for a high-performance engine build where reliability under extreme stress is paramount.

The crankshaft is forged from high-strength steel and balanced to ensure smooth operation at high RPMs. The 58-tooth reluctor wheel is standard for many LS applications, simplifying integration into your engine management system. The H-beam connecting rods are known for their strength and ability to withstand significant cylinder pressures, making them a popular choice for boosted or nitrous-fed engines. The included pistons are designed to work with this specific bore and stroke combination, offering a complete rotating assembly ready for professional assembly and tuning.

When building a performance LS engine, the rotating assembly is the heart of the operation. Choosing a robust, well-matched set like this Eagle Competition assembly means you're starting with components that are designed to work together and endure high-stress conditions. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and balancing procedures.
