Rocker Arm Shaft Spacer - 37.45 mm
Detroit Diesel

The rocker arm shaft spacer is a vital component that ensures the precise positioning of the rocker arm shaft, which plays a key role in controlling valve operation. Its length of 37.45 mm and diameter specifications are designed to fit snugly within the engine’s valve train assembly, providing stability and reducing unwanted movement. Constructed from thermoplastic, it offers excellent resistance to thermal expansion, chemical exposure, and mechanical wear, making it suitable for the rigorous demands of heavy-duty diesel engines. This spacer also contributes to smoother valve actuation, leading to more consistent combustion cycles and improved engine efficiency. Properly functioning spacers like this are essential for maintaining optimal valve timing, preventing valve train noise, and reducing wear on other components. Regular replacement with high-quality parts from Source One Parts Center ensures the durability and reliability of your engine’s valve train system.
