Valve Locks

Valve Locks are small yet crucial components within an engine's valvetrain system. Also widely known as a valve keeper, these semi-circular pieces play a vital role in securing the valve spring retainer to the valve stem. Their primary function is to maintain consistent valve spring tension, which is essential for proper valve operation and preventing any malfunction of the valve assembly. These components are generally crafted from high-strength steel, designed to withstand the significant forces within an engine.

The correct valve lock is paramount for engine integrity. While some may search for "valve lockout" in a different context, within the automotive world, the concern is the proper functioning of valve locks themselves. These small but mighty parts ensure that the valve and its spring remain correctly positioned. When performing engine work, particularly on the valvetrain, selecting the appropriate valve spring locks is critical for the long-term health and performance of your engine. Different applications and valve stem diameters require specific sizes, making it important to consult manufacturer specifications or a reputable source for the correct engine valve locks for your specific vehicle.
