ACL Race Series Bearings for Honda K20A / K24A
ACL Race Series performance engine bearings are recognized as the premier brand in the motorsport world. Race Series rod and main bearings are the standard components for championship-winning race engines, from Mexico to Bonneville, and from sport compact drift racing to small-block NASCAR, IHRA, and NHRA competitions. The unique combination of design, metallurgy, and engineering gives Race Series performance bearings a level of durability and performance that other products simply cannot match.
ACL Race Series performance engine bearings are manufactured to strict tolerances. Machined to micron tolerances supported by precision measuring systems, they provide consistent accuracy for critical characteristics such as wall thickness and crush. This ensures a secure fit and helps maintain consistent oil clearances.
Features
- Multi-layer construction provides many benefits, combining various characteristics to achieve high strength and superior seizure resistance.
- No flash plating is applied to further improve bearing retention and maximize heat transfer.
- Increased radial contact pressure improves bearing retention, keeping the bearing securely seated in the housing.
- ACL Race Series performance engine bearings feature increased eccentricity to improve shape adaptability, compensating for bore distortion during high-speed operation.
- The upper shells feature a full 180° groove, with matching partial grooves in the lower shells. This reduces the interruption of high-volume oil supply.
- Tapered groove run-out smooths the supply cutoff at the big end, avoiding pressure pulsation and cavitation.

Before Ordering
〇 Regarding Import Consumption Tax
At Shaftoya, 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 Confirmation of Compatibility
Our entire product database is based on North American vehicle specifications (USDM). Please confirm whether or not these products will fit your Japanese vehicle (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 it up for you.)
Please note that if you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Furthermore, please be aware that even if products are filtered by selecting the year, make, and model on our top page, it does not guarantee a direct fitment for Japanese market vehicles without modification.
All product descriptions have been translated into Japanese using translation software. As there may be confusing expressions, please contact us if you have any questions before ordering.
○ Regarding Delivery
Shipping costs are paid at the time of checkout. Estimates for shipping can be calculated automatically by entering your shipping address on the checkout page. For large items such as body parts, the automatic shipping calculation may occasionally differ significantly from the actual cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our warehouse in the United States. Unlike domestic shipping within Japan, international shipping takes approximately 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 delivery times. Note that all items are transported via air freight; they are not shipped by sea.
○ Regarding Japanese Vehicle Inspection Compliance
Essentially all products handled by our company are designed and manufactured outside of Japan. Please understand that they are not compliant with "Japanese vehicle inspection standards," and we cannot provide strength evaluation documents or similar certificates for that purpose. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and usage are at your own risk.
○ Regarding Warranty
Please check the contents of your order as soon as it arrives. Because all products are shipped internationally from outside of Japan, shipping damage to packaging or the product itself may occur. We will only provide returns, refunds, or replacements for items with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please understand that for products sold through our company, all warranty-related support will be handled "exclusively through us." We do not provide support through other companies or agents located within Japan.
