Superior clamping is essential to a long valvetrain life. And when it comes to sealing your valve spring retainers, only the strongest lock will do. By spreading the load of the spring force over a greater percentage, aftermarket valve stem locks are more reliable and lessen the chance of lock failure, which can lead to serious engine damage or at least a serious drop in vehicle value. Made from high-quality materials that have been machined and heat-treated for added strength, you'll find only premium valve locks for your engine at AutoAnything.
