30mm Race Master Exhaust Valve (Triple Groove) - Single from Manley Performance
Pro Flo versions, identified as Race Master and Race Flo valves, are manufactured from XH-426 material for exhaust and NK-842 material for intake. This valve series is intended for bracket, drag, and oval track racers operating at 8000 rpm or below. Generally, titanium valves are required for engine speeds above 8000 rpm.
Engine builders who have successfully used EV-8 alloy (21-4N) valves will find this series of Manley valves to be an excellent product at a very attractive price. The ultimate tensile strength tables on this and the following pages show that the Manley Race series is equal to the best offered by the competition.

Before Ordering
〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
All product databases are based on North American vehicles (USDM), so please check whether installation on Japanese vehicles (JDM) is possible before ordering. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to investigate for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer name, and vehicle model using the tabs on our top page, this does not necessarily mean they are compatible with Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of settlement. Estimates for shipping costs are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, the automatic shipping calculation may rarely differ significantly from the actual shipping cost. In such cases, we will contact you individually via email.
All products are basically shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please order with time to spare. If you are in a hurry, please contact us to confirm delivery dates in advance. All products are transported via airmail. They are not shipped by sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
All products we handle are basically designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents for this purpose. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and please install and use them at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside of Japan, there may be shipping damage to the packaging box or the product. Please understand that we will only provide returns, refunds, or replacement exchanges if you contact us within 7 days of receipt regarding products with shipping damage, defective products, or products different from your order. Furthermore, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please note that we do not handle matters through other companies or agents based in Japan.
