COMP Cams Groove Locks Retainer Kit

The COMP Cams Groove Locks Retainer Kit is a line of engine valve spring retainer keepers, also called valve locks or valve keepers. They secure the valve spring retainer to the valve stem. They are made for performance and race valvetrains and for demanding street builds.

Key Features:

• Wider-angle design: The wider lock angle spreads increasing valve spring loads over the retainer better than typical 7 degree locks. This reduces the chance of pull-through failure.
• Precision machined: Machined for accuracy and a consistent fit on the valve stem.
• Inside tang: The tang locates the lock, retainer and spring on the valve during assembly. The retainer taper nesting around the lock holds everything in place under spring load.
• Groove options: The line offers different groove configurations to suit different valve stem and application requirements.
• Brand backing: COMP Cams covers these locks with a 1 year limited warranty. They are made in the USA.

Valve locks must match the valve stem size. When installed correctly, a small gap remains between the two lock halves. Choose the lock that matches your valve and retainer, then compare the variants to find the right one for your engine build.
