Manley Platinum Series Pistons
There are some very good reasons why professional engine builders and elite tuners around the world use Manley pistons.
They are manufactured from durable, high-quality 2618 alloy forgings. They utilize "cam & barrel" profiles that are gentle on cylinder walls while producing high power. They use proprietary Total Seal piston rings. Manley's unique fixtures allow for skirt orientation and rotation. Ring groove machining can be performed in a single operation. This ensures the ultimate perpendicularity between the ring grooves and the skirt.

Before You Order
〇Regarding Import Consumption Tax
At Shaftoya Shopping Site, we pay the import consumption tax incurred at the time of import on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇Confirmation of Compatibility
All of our product databases are based on North American vehicles (USDM), so please verify 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 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, manufacturer, and model using the tabs on our top page, this does not necessarily mean they will fit 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 fees are paid at the time of checkout. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the automatically calculated shipping fee may occasionally differ significantly from the actual 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 within 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 check the delivery time. All products are transported via air freight; they are never shipped by sea freight.
○Regarding Compliance with Japanese Vehicle Inspection (Shaken)
The products we carry are fundamentally designed and manufactured outside of Japan. Please understand that they do not conform to the "Japanese vehicle inspection system," and we cannot provide documents such as strength calculation sheets for Japanese inspection purposes. Therefore, all parts are sold for the purpose of "use on circuits, private property, 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 is a possibility of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacement items for damaged products, defective products, or incorrect items if notified within 7 days of receipt. Please note that for products sold through us, warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
