SpeedFactory Valve springs / Steel retainer kit (Honda D-serie SOHC VTEC motoren)
80% 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.
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''.
SpeedFactory Valve springs / Steel retainer kit.
Upgrade your valvetrain in one complete package with the SpeedFactory Racing valve spring and retainer kit for Honda D-Series SOHC VTEC engines. Combining a full set of high-performance valve springs with matching lightweight retainers, this dual-component kit prevents valve float during aggressive high-RPM operation and elevated boost levels. The chrome silicon vanadium nickel alloy springs are double shot-peened for maximum fatigue resistance, while the precision-machined retainers significantly reduce overall valvetrain weight for faster engine revving and precise valve timing.
