Supertech VW 1.8L/2.0L 8V 7mm Stem (Race Only) Dual Valve Spring Kit (7mm stem)

The 7mm stems on these Supertech dual valve springs are a key detail for high-RPM engine builds. This kit is specifically intended for race applications where the engine will be pushed hard and often. These springs are designed to handle the increased stresses and demands of racing, ensuring reliable valve control at higher engine speeds.

This well-built dual spring kit uses strong materials to manage valve float, which is crucial when you're running aggressive camshafts or pushing your 1.8L or 2.0L 8-valve VW engine beyond its stock limits. The dual spring design offers better stability and dampening compared to single springs, helping to keep the valves seated properly during rapid open-close cycles. This improved control is essential for maintaining engine power and preventing damage under race conditions.

When building a dedicated race engine, using components like this Supertech valve spring kit is important for achieving optimal performance and durability. Always consult your camshaft manufacturer's specifications to ensure these springs are the correct match for your chosen cam profile and intended RPM range.
