Valve springs are one of the most critical and most overlooked components in an engine. Valve springs play an important role in controlling the breathing in a diesel engine. The valves open mechanically by a camshaft, and are closed by the tension of the valve springs. When considering that a typical diesel engine valve is opening and closing hundreds of millions of times during its life cycle, it is imperative that valve springs be replaced during the next overhaul to attain the best performance from your engine. Improper selection of the wrong valve spring is one of the most common causes of engine failure. We have the most complete election of high quality valvetrain components in the industry.
