Valve Spring Kit

Cylinder head valve springs are components that are typically made of high-strength steel wire and are used to control the opening and closing of the engine's valves. Valves are critical components of an internal combustion engine that allow fuel and air to enter the combustion chamber and exhaust gases to exit. The valve spring is responsible for returning the valve to its closed position after it has been opened by the engine's camshaft or other connecting valvetrain components. When the camshaft opens the valve, the valve spring is compressed, allowing the valve to open and admit fuel and air into the combustion chamber or allow exhaust gases to exit. When the camshaft releases the valve, the valve spring returns the valve to its closed position, sealing the combustion chamber and ensuring that no fuel or air escapes. Valve springs come in a variety of sizes and strengths, depending on the specific requirements of the engine and camshaft. They must be strong enough to resist the force of the camshaft and return the valve to its closed position quickly and reliably, but also light enough to prevent excessive wear on the camshaft and valve components. By controlling the opening and closing of the engine's valves, springs help to ensure that the engine runs smoothly and efficiently, while also providing protection against damage to valve components.

When selecting valve springs for your engine, first confirm the correct size and type to match your camshaft, which is available from the camshaft manufacturer. Next, confirm the outside diameter of the valve springs will fit into the cylinder head pockets, as machining will be required if the springs do not fit. From the remaining compatible options, select the kit that fits your application and budget needs. A valve spring and retainer kit is popular by many as it includes matching retainers and keepers / locks to ensure proper installation and operation of the valves.
