COMP Cams Titanium Set of 16 – 10 Degree, 5/16in, Single Groove Locks with Lash Cap Recess 637-16

These Titanium Super Locks™ with lash cap recess feature a 10° lock angle and 5/16″ valve stem size. They are recommended for all race applications because Titanium Super Locks™ have a wider angle (10°) that better distributes the ever increasing valve spring loads over the retainer than typical 7° locks.
