1991–2010 Dodge Viper Race Master Intake Valves - Set of 10 by Manley Performance
The Race Master, and Pro Flo versions identified as Race Flo valves, are manufactured from XH-426 material for exhaust and NK-842 material for intake. This series of valves is intended for bracket, drag, and oval track racers operating at or below 8000 rpm. Generally, engine speeds above 8000 rpm require titanium valves.
Engine builders successfully using EV-8 alloy (21-4N) valves will find that this series of Manley valves is an excellent product at a very attractive price. The ultimate tensile strength tables on this and the following pages demonstrate that the Manley Race series is equal to the best offered by the competition.

Before Placing an Order
〇 Regarding Import Consumption Tax
At Shaft-ya 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 you pay at checkout.
〇 Confirmation of Compatibility
Because our entire product database is based on North American vehicles (USDM), please confirm whether or not these parts can be installed on Japanese vehicles (JDM) before placing your order. (If you are unsure if the listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look it up for you.)
If you place an order without confirming compatibility, we will be unable to accept returns due to incompatibility.
Additionally, please note that even if products are sorted by selecting the year, manufacturer, and vehicle model using the tabs on our top page, this does not necessarily mean they are compatible with Japanese-spec vehicles without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of payment. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.
In principle, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow yourself enough time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air freight; they are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection (Shaken) System," and we are unable to provide strength calculation documents or similar paperwork for these purposes. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally from outside of Japan, packaging and products may sustain shipping damage. We will only provide returns, refunds, or replacement exchanges for damaged items, defective products, or items different from what was ordered if you contact us within 7 days of receipt. Please understand that for products sold through our company, all warranty-related matters must be handled "solely through us." We do not provide support through other companies or distributors located within Japan.
