ACL Race Series Bearings for Honda B-Series

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 record-setting and championship-winning race engines, from Mexico to Bonneville, 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. Machining to micron tolerances, supported by precision measurement systems, ensures consistent accuracy for critical characteristics such as wall thickness and crush. This ensures a secure fit and maintains consistent clearance.

Features

  • Multi-layer construction provides many benefits, including 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, securing the bearing in the housing
  • ACL Race Series performance engine bearings feature increased eccentricity to improve shape adaptability for compensating for bore distortion during high-speed operation
  • The upper shells have a full 180° groove, matching a partial groove in the lower shells. This reduces the interruption of oil supply to the big end
  • Tapered groove run-out smoothes the oil supply cut-off at the big end, avoiding pressure pulsations and cavitation

    Before Ordering

    〇 Regarding Import Consumption Tax
    At Shaft-ya, we pay the import consumption tax on your behalf at the time of import, so there will be no additional charges beyond the total amount paid at checkout.

    〇Confirmation of Compatibility
    All of our product databases are based on North American vehicle (USDM) specifications. Please verify compatibility with your Japanese market 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 investigate for you.)
    We cannot accept returns due to incompatibility if an order is placed without confirming compatibility.
    Please note that even if products are sorted by selecting the year, make, and model using the tabs on our homepage, it does not necessarily guarantee that they will fit a Japanese market vehicle without modification.
    All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us with any questions before placing your order.

    ○ Regarding Shipping
    Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the automated calculation. In such cases, we will contact you individually by email.

    In principle, 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 allow plenty of time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Please note that all products are transported by air freight; they are never shipped by sea.

    ○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
    Generally, all products we handle are designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide strength calculation documents or similar paperwork for these systems. Therefore, all parts are sold for the purpose of "circuit, private property, or off-road use," and installation and use are at your own risk.

    ○ Regarding Warranty
    Please inspect the contents immediately upon arrival. Because all products are shipped internationally from outside Japan, there may be instances of shipping damage to the packaging or the product. We will only provide returns, refunds, or replacements for products with shipping damage, defective products, or incorrect items if you notify us within 7 days of receipt. Please understand that for products sold through our company, warranty service will be handled "exclusively through us." We do not provide services through other companies or distributors located within Japan.
