37mm Race Master Intake Valves (Triple Groove) - Set of 8 by Manley Performance

The Race Master, as well as the 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 8000 rpm or less. Generally, engine speeds above 8000 rpm require titanium valves.

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 most attractive price. The ultimate tensile strength charts on this and the following pages demonstrate that the Manley Race series is equal to the best offered by the competition.

Before Ordering

〇 About 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 will be no additional charges other than the total amount paid at checkout.

〇 Checking Compatibility
All product databases are based on North American vehicles (USDM). Please confirm compatibility with Japanese vehicles (JDM) before ordering. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will check 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, and vehicle model in the tabs on our top page, it does not necessarily mean they will fit 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 Delivery
Shipping costs are paid at the time of checkout. Regarding shipping estimates, they are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where there is a significant discrepancy between the automatically calculated shipping amount and the actual shipping cost. In that case, we will contact you individually via email.

Basically, all products are shipped internationally from our US warehouse. Unlike domestic Japanese delivery, international delivery takes about 7 to 14 days, so please order with enough time to spare. If you are in a hurry, please contact us in advance to check the delivery time. All products are transported by air mail. We do not use sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Basically, all products handled by our company are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation documents or the like for the Japanese inspection system. 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. Since all products are shipped internationally from outside Japan, there may be damage to the packaging box or the product due to shipping. 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, regarding products sold through our company, warranty-related support will be handled "exclusively through our company." Please note that we do not handle support through other companies or distributors located in Japan.
