ACL Race Series Bearings for Mitsubishi 4G93
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 component for record-breaking and championship-winning race engines, from Mexico to Bonneville, and from sport compact drift racing to small-block NASCAR, IHRA, and NHRA competitions. Through a unique combination of design, metallurgy, and engineering, Race Series performance bearings offer durability and performance that other products simply cannot match.
ACL Race Series performance engine bearings are manufactured to strict tolerances. Machining with micron tolerances, supported by precision measuring 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, such as combining various properties 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 secured in the housing
- ACL Race Series performance engine bearings feature increased eccentricity to improve shape adaptability to compensate for bore distortion during high-speed operation
- The upper shell has a full 180° groove, with a matching partial groove in the lower shell. This reduces interruptions in high-volume oil supply
- Tapered groove run-out smooths the oil supply cut-off at the big end, avoiding pressure pulsations and cavitation

- Mitsubishi 4G93
- Lancer, Mirage, FTO
- Volvo S40, V40

Before Ordering
〇 Regarding Import Consumption Tax
At the Shafutoya 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 Checking Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm whether the item can be installed on a 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 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 selecting the year, manufacturer, and model using the tabs on our top page, this does not necessarily mean they are compatible with Japanese-spec models 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 Delivery
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 automatically calculated shipping cost may occasionally differ significantly from the actual cost. In such cases, we will contact you individually by email.
Generally, all products are shipped internationally from our warehouse in the United States. Unlike domestic shipping in Japan, international delivery takes approximately 7 to 14 days, so please allow ample time when ordering. If you are in a hurry, please contact us to confirm the estimated delivery time in advance. Please note that all products are transported by air; they are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are essentially designed and manufactured outside of Japan. They do not comply with the "Japanese Vehicle Inspection System," and we are unable to provide strength calculation sheets or similar documents for that purpose. 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 may be cases of shipping damage to the packaging or the product itself. We only accept returns, refunds, or replacements for products with shipping damage, defective goods, or items different from what was ordered if you contact us within 7 days of receipt. Please understand 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.
