90% of the products in our store are in internal or external stock and we can often process your order quickly (varying from a few hours to a number of business days).
Naturally it is possible that a product has an (unexpected) longer delivery time.
Upon receipt of your order, we will always inform you about this and offer any available alternatives. So keep a close eye on your mailbox.
We deliberately provide stock information about our products afterwards, because many suppliers do not offer a ''stock link system'' and we do not want to show '' estimates '' in advance, like many other webshops do (which are often incorrect and give you wrong information in advance). We only want to give our customers actual information on the moment of processing the order so we don't mislead our customers.
If you need a product VERY quickly and you need to be sure that we have it in stock, please e-mail or call us or send a message via ''ask a question about this product'' below in the product description.

Supertech understands that each motor is unique in its requirement and demands. There fore Supertech offers valves in a range of materials to suit any motor.
Stainless – Made as a one piece forged valve for higher strength and reliability. Supertech uses mostly EV8 (21-4N) for Intake and Exhaust Valves, however there are other alloys that are used with different heat treatments to manufacture Valves for specific applications.
Black Nitride – This is a hardening treatment that provides a smooth surface then chromed valves and produces less friction between stem and guide.
