ACL Race Series Connecting Rod 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 achieve what drivers expect from high-performance trimetal bearings. These ACL Race Series performance engine bearings go the distance.
ACL Race Series performance engine bearings are manufactured to strict tolerances, with special attention paid to wall thickness precision. This ensures a reliable fit and helps maintain consistent clearances.
Features
- High-strength lead, tin, and copper overlay plate with reduced thickness
- Hardened steel backing for improved bearing retention
- Nickel barrier layer and high-fatigue strength copper-lead lining
- Elimination of flash plating on the back of the bearing
- Increased eccentricity to compensate for bore distortion at high RPM
- 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-grey appearance of regular aftermarket bearings because they do not have a final silver tin flash applied. The silver tin finish applied to other bearings can migrate with the plate under high load and heat, potentially causing high spots on the back of the shell and distorting the bearing.

Before Ordering
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 there will be no additional charges beyond the total amount paid at checkout.
〇Checking Compatibility
Our entire product database is based on North American specification vehicles (USDM), so please verify compatibility with Japanese specification vehicles (JDM) 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 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, it does not necessarily guarantee a direct, unmodified fit for Japanese model vehicles.
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 Delivery
Shipping costs are paid at the time of settlement. Estimates for shipping costs are calculated automatically when 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.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow yourself plenty of time when ordering. If you are in a hurry, please contact us in advance to confirm the delivery date. All products are transported via air freight. They are not shipped by sea.
○Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation documents or similar paperwork 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. 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 products with shipping damage, defective products, or items different from what you ordered if you contact us within 7 days of receipt. Please note that for products sold through us, warranty support will be provided "exclusively through us." We do not provide support through other companies or distributors located within Japan.
