Designed for maximum endurance in roller cammed Oval Track, Road Racing and Drag Racing applications where maximum locking force with the valve stem is required. These heavy-duty valve locks are also machined from 4140 Chrome Moly Bar-Stock and heat treated like our standard 7°. Super 7° Valve Locks incorporate a ground finish on the O.D. which allows a more consistent installed height for each retainer on its valve. Super 7° deg. valve locks are used in conjunction with Isky Super 7° retainers only.
