ACL 4AGEC bearings offer a unique combination of design, metallurgy, and engineering. These qualities combine to deliver what drivers and engine builders expect from high-performance Trimetal engine bearings. These Race Series bearings are designed to withstand higher RPM conditions.
Features
- High-strength overlay plate with reduced thickness for improved fatigue properties
- Hardened steel backing on all connecting rod bearings to improve support for the bearing lining and facilitate bearing retention within the housing.
- Increased crush for improved bearing retention.
- Elimination of flash plating on the back of the bearings to improve heat transfer through the bearing and maximize grip between the bearing and the housing.
- Increased eccentricity to compensate for bore distortion at high RPM and to assist in the formation of a hydrodynamic oil film.
- Tight and consistent wall tolerances to maintain consistent clearances.
- Enlarged ID chamfer on bearing edges to accommodate the large fillet radii of performance crankshafts.
Before You Order
〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we cover the import consumption tax incurred at the time of import, so there will be no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
All product databases are based on North American vehicles (USDM), so please verify compatibility with Japanese vehicles (JDM) before placing your order. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look into it 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 using the tabs on our top page, this does not guarantee that they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so if you have any questions, please contact us before ordering.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Estimates for shipping costs 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 cost and the actual shipping cost. In such cases, we will contact you individually via email.
Basically, all products are 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 when ordering. If you are in a hurry, please contact us in advance to confirm the delivery date. Note that all products are transported by air mail. They are not shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are basically designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide documents such as strength evaluation reports for the Japanese inspection system. Therefore, all parts are sold for "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 shipping damage to the packaging or the product. Please understand that we will only provide returns, refunds, or replacements for products with shipping damage, defective products, or items different from what was ordered if you contact us within 7 days of receipt. Please note that for products sold through our company, warranty support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
