Engle Dual Valve Springs - Type 1 Engines

This heavy duty dual valve spring set from Engle is designed for all VW Type 1 aircooled engines, offering superior valve control for high-performance and high-RPM applications. Dual valve springs use an inner and outer spring working together to provide increased seat and open pressure, significantly reducing the risk of valve float and maintaining precise valve timing under aggressive cam profiles.

Engineered to Engle’s exacting standards, these springs are manufactured for strength, consistency, and durability, making them ideal for engines running performance or race camshafts, higher RPM limits, and heavier valve train loads. The dual spring design also improves harmonic control within the valve train, enhancing reliability at sustained high engine speeds.

These springs are commonly paired with chromoly valve retainers and heavy duty valve cotters to ensure maximum strength and safety. Due to the increased spring pressures, it is essential to check installed height, coil bind, and valve guide clearance, as some cylinder heads may require machining for correct dual spring fitment.

Supplied as a set of 8, this kit provides enough dual spring assemblies to fully equip one complete Type 1 aircooled engine.
