ACL HX-Series: Extra Oil Clearance Main Bearings

For high-performance Mitsubishi 4G63 and 4G64 engines, managing oil clearance is critical to preventing bearing failure under extreme conditions. The ACL HX-Series main bearings are engineered with slightly increased oil clearance, allowing for better cooling and lubrication in high-horsepower, high-boost applications. These bearings are the preferred choice for builders looking to optimize oil flow through the crankshaft.

Engineered for High-Output Engines:

• HX-Series design for increased oil flow
• Tri-metal construction for enhanced load support
• Ideal for high-RPM and racing applications
• Precision tolerances for consistent performance
• Compatible with 7-bolt 4G63/4G64 engines

When you push your engine beyond factory specifications, heat management becomes the primary challenge. The extra oil clearance provided by these ACL bearings helps mitigate heat buildup, ensuring that your crankshaft journals remain properly lubricated even under the most demanding conditions. This set is essential for anyone building a high-output engine where reliability is just as important as power.
