What is the main advantage of dual valve springs for drag racing?

Dual valve springs offer increased stability and control over the valve at high RPMs. This helps prevent valve float, ensuring more consistent engine performance during demanding drag racing conditions.

Are these springs suitable for street use?

These NexTek Series springs are specifically designed for drag racing applications where high valve lift and RPMs are common. For street use, a different spring designed for milder applications might be more appropriate.

What other components are typically needed when installing new valve springs?

When installing new valve springs, it's often recommended to also check or replace valve seals, retainers, and keepers. Consulting your engine builder or a qualified mechanic is advised to ensure all necessary components are accounted for.
