Eagle Chevy LS1 3.800in Crank 58 Tth Reluctor 6.125in H-Beam -29cc 3.903in Pistons Rotating Assembly

Starting with a 3.800-inch stroke crankshaft, this Eagle rotating assembly is built for serious performance applications, especially those involving forced induction or nitrous oxide. The crankshaft is forged from 4340 steel, a strong material chosen for its ability to handle high stress and torque, making it a solid foundation for a powerful LS1 engine build. It features a 58-tooth reluctor wheel, which is standard for many LS1 applications, ensuring proper crank signal for the engine control unit.

Complementing the crankshaft are 6.125-inch long H-beam connecting rods, also forged from 4340 steel. The H-beam design is well-known for its strength-to-weight ratio, providing the rigidity needed to withstand the intense pressures generated during high-RPM operation and heavy loads. These rods are paired with pistons designed for a -29cc dish volume, which helps achieve a specific compression ratio when combined with the cylinder heads and bore size. The pistons themselves measure 3.903 inches in diameter, fitting the standard bore for many LS1 variants.

This assembly is intended for competition use and is not CARB approved, meaning it cannot be legally shipped to California. It's a comprehensive package designed to give your LS1 engine the robust internal components it needs to perform at its best under demanding conditions. Ensure you consult with your engine builder or refer to detailed LS1 engine assembly guides for proper installation and balancing procedures, as rotating assemblies typically require balancing to the specific vehicle and intended use.
