Heavy Duty Single Valve Springs - Type 1 Engines

High rev single valve spring set for Volkswagen Type 1 aircooled engines. Designed as an upgrade over standard factory valve springs, these springs provide improved valve control at higher engine speeds, helping to reduce valve float and maintain accurate valve timing.

Ideal for performance street engines, mild performance camshaft applications and rebuilt engines that regularly see higher RPM than standard. These springs offer increased spring pressure without the complexity of dual spring setups, making them a popular choice for fast road and mild performance builds.

Manufactured to provide consistent valve control and reliability, they can be used on all Type 1 based engines when the correct installed height and valve train geometry are maintained.
