When building a performance engine, the rotating assembly is critical for power and durability. This Eagle kit provides a well-matched set of components that work together. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and balancing procedures.
