Speedmaster Valve Lock Keepers

Strong Valve Locks for Racing

Speedmaster Valve Lock Keepers are wider-angled to distribute the ever-increasing valve spring loads over the retainer better by reducing the chance of "pull-through" failure. They are machined from Chromoly steel, heat-treated for maximum strength, and designed with a 10-degree taper. These valve locks will fit any PCE 10-degree retainer and are recommended for all race applications due to their superior strength.
