About this part

Product Details

This is the Eagle Chevy LS2/LS3 3.800-inch crankshaft, 6.125-inch H-beam connecting rod, and 4.005-inch piston rotating assembly. It’s a complete package designed to be the heart of a high-performance engine build for your LS2 or LS3 Chevrolet. A rotating assembly is essentially the engine's core moving parts – the crankshaft, connecting rods, and pistons – all balanced and ready to be installed. Getting these critical components as a matched set from a reputable manufacturer like Eagle ensures they work together harmoniously, which is crucial for reliability and power, especially when you're pushing the limits.

Eagle has put together this competition-grade assembly with serious performance in mind. The 3.800-inch stroke crankshaft is forged for strength, giving you a solid foundation for significant power. Paired with it are 6.125-inch H-beam connecting rods, known for their robust design and ability to handle high loads and RPMs, making them a popular choice for boosted or nitrous applications. The assembly includes 4.005-inch pistons, ready for your chosen compression ratio and ring package. This entire setup is balanced, saving you a significant step and potential for error during the engine building process. It's built to withstand the demands of racing, including the extra stress from nitrous oxide or forced induction systems.

When you're building an engine for racing, especially with plans for nitrous or turbocharging, the quality and strength of your rotating assembly are paramount. This Eagle assembly is a well-built option that addresses those needs directly. It's important to note that this part is not CARB approved and cannot be shipped to California due to emissions regulations. Always refer to the manufacturer's detailed specifications and installation instructions to ensure proper fitment and assembly with your specific engine block and cylinder heads.
