Valve Spring Retainer Cap
Detroit Diesel

The valve spring cap acts as a spring retainer, securing the valve spring in place on the cylinder head. With an outer diameter of 28.50 mm and an overall length of 11 mm, it fits snugly over the valve stem, ensuring consistent spring tension and preventing valve float during high RPM operation. Made from durable steel, this component withstands repeated compression cycles and high temperatures common in diesel engines. Its role is critical in maintaining proper valve closure and timing, directly influencing engine efficiency and emissions. Properly securing the valve spring with a high-quality retainer reduces the risk of valve failure, which can lead to catastrophic engine damage. When selecting this part, sourcing it from a reliable supplier like Source One Parts Center ensures material integrity and precise manufacturing, safeguarding engine performance in heavy-duty applications.
