Manley Sports Compact Valve Springs
Manley Performance valve springs are specifically designed to withstand the rigors of today's aftermarket sports compact camshafts and ensure proper valvetrain control in high-RPM sports compact engine applications. This means using only the finest super-clean chrome silicon high-tensile steel alloy, followed by refined heat treatment and shot-peening to ensure maximum fatigue life and limit load loss. Manley valve springs are wound from extremely clean alloy. Each design minimizes stress to guarantee a long service life for high-lift camshafts.

Before You Order
○ Regarding Import Consumption Tax
At the 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 beyond the total amount paid at checkout.
○ Confirmation of Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm whether the product can be installed on a Japanese domestic vehicle (JDM) before ordering. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to check for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, make, and model on our top page tabs, it does not necessarily guarantee a direct fit for Japanese model 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 settlement. Estimates for shipping costs are calculated automatically when you enter your delivery 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.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic shipping within Japan, international shipping takes approximately 7 to 14 days, so please allow sufficient time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all items are shipped via air freight. Products are never shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide structural strength documentation or similar paperwork for these purposes. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road use," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents of your order immediately upon arrival. As all items are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. Please understand that we only accept returns, refunds, or exchanges for products with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Furthermore, for products sold through us, warranty support will be provided "exclusively through us." Please note that we do not coordinate with other companies or agencies based in Japan for warranty claims.
