ACL Race Series Extra Clearance Main Bearings

For high-horsepower 4B11T builds, managing oil film thickness is vital. These ACL Race Series main bearings with extra oil clearance are designed to provide the additional space required for high-load, high-RPM environments, ensuring your Mitsubishi Evo X engine stays lubricated under extreme stress.

Why Choose Extra Clearance Bearings?

• Enhanced Oil Flow: The 'HX' specification provides increased clearance, allowing for better cooling and lubrication of the crankshaft journals.
• Race-Proven Durability: Constructed with a hardened steel backing and a high-strength overlay to resist fatigue.
• Optimized for Performance: Ideal for engines running larger turbos, increased boost, or sustained high-RPM track use.
• Direct Fitment: Engineered specifically for 2008-2015 Mitsubishi Lancer Evolution GSR and MR engines.

Building a high-performance engine requires attention to detail, especially regarding bearing clearances. These ACL bearings minimize the risk of oil starvation and heat buildup, common issues in modified 4B11T engines. Ensure your engine build is ready for the track with high-quality components from GGCRACING.
