Valve Spring Retainers
SUPERGRIP - Single Groove Valve Locks (set of 16)
SUPERGRIP Single Groove 7° Locks are machined from billet steel, Carbon Nitraded, and then heat treated.
The single groove design is far superior to the standard 3 groove VW design, and will outlast it many times over, without the wear and tear normally caused by standard VW valve locks. SUPERGRIP Single Groove Locks are for use only with SUPERGRIP Single Groove Valves and Chromoly Retainers.
