Eagle Chevy LS1 3.900in Crank 58 Tth Reluctor 6.125in H-Beam -15cc 3.903in Pistons Rotating Assembly

This Eagle Competition Rotating Assembly starts with a 3.900-inch stroke crankshaft, designed for Chevy LS1 engines. The crankshaft features a 58-tooth reluctor wheel, which is standard for many LS1 applications, ensuring proper sensor readings for engine management. This assembly is built for demanding use, including racing scenarios that might involve nitrous oxide or forced induction, indicating its robust construction and ability to handle higher stress levels.

The assembly includes 6.125-inch long H-beam connecting rods. H-beam rods are well-known for their strength and rigidity, making them a popular choice for high-performance builds where durability under significant load is critical. Paired with these rods are pistons featuring a -15cc dish volume and a 3.903-inch bore size. This specific dish volume is designed to achieve a particular compression ratio when combined with the chosen cylinder heads and crankshaft stroke, which is crucial for optimizing power output and engine response in a performance application.

This is a comprehensive rotating assembly, meaning it includes the crankshaft, connecting rods, and pistons, all balanced as a set by Eagle. This balanced rotating assembly is essential for smooth operation and longevity, especially at higher engine speeds. It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Always consult with your engine builder or refer to manufacturer specifications for installation details and compatibility with other engine components.
