Supertech VW 2.0L 16V Titanium Retainer 7mm Valve Stem Single Groove

If you're rebuilding the top end of your VW 2.0L 16V engine, especially for performance applications, you'll want to pay close attention to the valve train components. This Supertech titanium retainer is designed to work with 7mm valve stems and single groove keepers. Titanium is a strong, lightweight material that helps reduce the overall mass in the valvetrain, which can lead to improved responsiveness at higher RPMs.

This retainer is a well-built piece from Supertech, a company known for its engine components. It's made from titanium, which is significantly lighter than steel retainers. This weight reduction is important because it lowers the inertia of the valve spring assembly, allowing it to follow the camshaft profile more accurately, especially as engine speeds increase. The single groove design is standard for many performance valve spring setups.
