The Cylinder Head Outer Valve Spring is designed to regulate the movement of engine valves during the combustion process. This spring exerts a controlled force on the valves to ensure the valves open and close at the right moments, facilitating the intake of air and fuel and the expulsion of exhaust gases. Its role is to maintain proper valve timing for the engine to operate smoothly and deliver consistent power.Attributes:• Made from high-quality, durable materials.• Enhances the reliability of the valve train system.• Has a free length of 76.15mm.Applications: The Cylinder Head Outer Valve Spring is positioned around the valve stem and installed within the cylinder head. This allows it to control the movement of the engine valves by applying the necessary force to ensure proper opening and closing during the combustion process.
