Supertech Dual Valve Spring Kits are a great idea for any Seadoo owner who has increased their maximum RPM and is looking to reduce some of the stress on their engine.

All Supertech valve springs are made with premium Superclean Chrome Silicon Vanadium Steel alloy for higher performance & durability at high RPMs. Using high quality steel alloy also provides the added benefit of better structural memory for all Supertech springs.

These valve springs are computer designed to ensure that wire stress levels do not overpass the limits of stress defined in the diagrams of fatigue. We also utilise computer software that allows us to ensure that the harmonics are under control. This combined with our high quality steel alloy enables Supertech valve springs to be more durable in extreme conditions, giving your performance racing engine a serious competitive advantage in both performance and durability.

A great option for performance engines with a heavy valve-train. Dual Valve springs rub against each other and act as a damper. The second spring also acts as a safety measure. as broken springs can be found before they drop a valve into the engine.
