ACL Race Series Main Engine Bearings
High-performance driving requires the best parts. Trust ACL Race Series performance engine bearings to deliver the performance that meets the rigorous racing standards you expect. They provide the reliability to withstand even higher RPM conditions. A unique combination of design, metallurgy, and engineering comes together to deliver what drivers expect from high-performance tri-metal bearings. These ACL Race Series performance engine bearings are built for the long haul.
ACL Race Series performance engine bearings are manufactured to strict tolerances with particular attention paid to wall thickness accuracy. This ensures a secure fit and allows for the maintenance of consistent clearances.
Features
- High-strength lead, tin, and copper overlay plate with a reduced thickness
- Hardened steel backing to assist with bearing retention
- Nickel barrier layer and high fatigue strength copper-lead lining
- Elimination of flash plating on the bearing backs
- Increased eccentricity to compensate for bore distortion at high RPM
- 3/4 grooved main bearings to optimize bearing load and oil flow to the connecting rod bearings
- Precision machined for consistent wall tolerances
- Enlarged ID chamfer on bearing edges to accommodate performance crankshafts
Please Note
ACL RACE Series performance engine bearings do not have the silver-gray appearance of regular aftermarket bearings because the final silver tin flash has not been applied. The silver tin finish applied to other bearings can migrate with the plate under high loads and heat, creating high spots on the back of the shell and potentially distorting the bearing.

Before Ordering
〇 About Import Consumption Tax
At Shaftoya Shopping Site, we cover 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.
〇 Compatibility Confirmation
Our product database is primarily based on North American vehicles (USDM). Please verify whether the product can be installed on a Japanese vehicle (JDM) before placing your order. (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 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 items are sorted by year, manufacturer, and vehicle 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 costs are paid at the time of settlement. An estimate for shipping costs will be calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where the automatically calculated shipping cost differs significantly from the actual cost. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please order with time to spare. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air. They are never shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are 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 reports for the Japanese inspection system. 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. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging box or the product itself. Please understand that we will only provide returns, refunds, or replacement products if you contact us within 7 days of receipt regarding damaged, defective, or incorrect items. Please note that for products sold through our company, warranty support will be provided "only through our company." We do not provide support through other companies or distributors located within Japan.
