Super 7° Chrome Moly Valve Locks (Set) For 5/16" Valve Stem Applications, STD Height

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° valve locks are used in conjunction with Isky Super 7° retainers only.
