Supertech VW 16V Single Groove Valve Lock (Req 2 Per Valve) - Set of 8

These single groove valve locks from Supertech are made from hardened steel, a strong material that holds up well under the stress of engine operation. You'll need two of these per valve, so this set of eight is enough for four valves, typically covering one intake and one exhaust valve per cylinder on a 16-valve engine. They are designed to securely hold your valve springs in place, ensuring proper valve timing and sealing.

When you're rebuilding the top end of your VW 16V engine, using well-made components like these valve locks is important for reliability. They are a direct replacement for your stock locks, fitting right into the valve spring retainers. The single groove design is a common and effective way to keep the valve train assembled correctly.
