COMP Cams Super Locks with recess for 5/16" (.310") valve stems use a 10-degree lock angle to distribute spring load more evenly over the retainer than 7-degree designs. These steel Super Locks come in a 16-count package and include the lash cap recess for setups requiring that accommodation. They are intended for demanding valve train applications where secure retention is essential.
