Manley pistons are machined from high-strength 2618 alloy. Each design is lightweight yet robust enough to ensure a long service life. They feature an offset wrist pin design for quiet startup. Our unique "one-fixture" manufacturing process ensures perfect ring groove and skirt perpendicularity, maximizing horsepower. All pistons come with moly-coated skirts. Total Seal round wire locks, premium chromoly wrist pins, and premium steel top ring sets are included in all kits at no extra charge. Upgraded 9310 alloy wrist pins are available.
Before Ordering
〇 Regarding Import Consumption Tax
At Shaftoya Shopping Site, we cover the import consumption tax incurred at the time of import, so there are no additional charges beyond the total amount paid at checkout.
〇 Compatibility Check
Our entire product database is based on North American market (USDM) vehicles, so please verify compatibility with Japanese market (JDM) vehicles before ordering. (If you are unsure whether a listed product fits your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If an order is placed without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, make, and model using the tabs on our top page, this does not necessarily mean they will fit Japanese model vehicles without modification.
All product information has 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 checkout. Shipping estimates are calculated automatically once 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 cost. In such cases, we will contact you individually via email.
Essentially, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping within Japan, international delivery 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 check delivery times. Note that all products are transported by air; they are never shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compliance
Basically, all products we handle are designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese Vehicle Inspection (Shaken) System," and we are unable to provide documents such as strength evaluation reports for that purpose. Therefore, all parts are sold for use on "circuits, private property, and off-road," and installation and usage are at your own risk.
○ Regarding Warranty
Please check the contents of your order 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 exchanges for shipping-damaged items, defective products, or incorrect items if notified within 7 days of receipt. Please also note that for products sold through us, all warranty-related support will be handled "exclusively through our company." We do not coordinate with other companies or agencies located within Japan.
