ACL Race Series Main Bearing Set for SR20DE / SR20DET
ACL Race Series performance engine bearings are recognized as a premier brand in the world of motorsports. Every Race Series bearing is a powerful component that supports race engines that have captured championships in various racing series, including the Bonneville Speed Week, Time Attack, and drift racing.
Race Series performance bearings possess durability and performance that are impossible to find in other products.
ACL Race Series performance engine bearings are machined and manufactured to micron-level accuracy using a precision measurement system, achieving consistent precision for critical characteristics such as wall thickness and crush. This ensures a secure fit and allows for the maintenance of necessary, consistent clearances.
Features

Before Ordering
〇 Regarding Import Duties
At the Shaftoya shopping site, we pay the import duties incurred during customs clearance on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇 Confirmation of Compatibility
Our entire product database is based on North American (USDM) vehicles; please verify whether or not the product can be installed on a Japanese (JDM) vehicle before placing your order. (If you are unsure whether the 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, manufacturer, and vehicle model via 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. Estimates for shipping fees are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, the automatically calculated shipping fee may rarely differ significantly from the actual cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please contact us in advance to confirm the delivery date. Note that all products are transported by air; they will never be shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese vehicle inspection system," and we cannot provide documents such as strength calculation reports for Japanese vehicle inspections. 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, packaging boxes or the products themselves may sustain damage during transit. Please understand that we only provide returns, refunds, or replacement exchanges for items with transit damage, defects, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through us, all warranty-related support will be handled "exclusively through us." Please note that we do not handle support through other companies or distributors located within Japan.
