Supertech BMW / VW 7mm Stem Triple Groove Hardened 7 Degree Valve Lock (Req 2 Per Valve)

These Supertech valve locks are made from hardened steel, which means they're built to last under the stress of engine operation. They feature a triple groove design and are set up for a 7-degree valve stem angle, a common setup for many BMW and VW engines. Each valve requires two of these locks to hold the valve spring retainer in place.

The hardened steel construction is key here, as it resists wear and deformation, ensuring your valves stay properly seated. The triple groove design offers a secure grip on the valve stem, and the 7-degree angle is specific to certain engine designs, so it's important to confirm this matches your application. If you're rebuilding a cylinder head or replacing valve components on a compatible BMW or VW, these locks are a solid option for ensuring proper valve function.
