Eagle Chevrolet 403 3.766in Forged 4340 Steel Crank 6.135in H-Beam Balanced Rotating Assembly

If you're building a high-performance Chevrolet engine from the ground up, a strong rotating assembly is the heart of the operation. This balanced rotating assembly from Eagle is built around a forged 4340 steel crankshaft with a 3.766-inch stroke, designed to handle the demands of serious power. It includes 6.135-inch H-beam connecting rods, also made from robust 4340 steel, which are known for their strength and reliability under high stress.

Eagle has balanced this assembly to reduce vibration and improve overall engine smoothness, which is crucial for longevity and performance, especially when you're pushing the limits. The use of 4340 steel for both the crankshaft and connecting rods means you're getting a well-built foundation that can withstand significant horsepower and torque. This is the kind of component that serious engine builders rely on when they need a rotating assembly that won't let them down.

This assembly is a complete rotating package, meaning it's ready to be installed into your engine block once you've prepared it. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications to ensure optimal performance and durability.
