• Standard size bearing set with identical bearing halves for simplified installation
• Advanced material composition with optimized dynamic thickness for improved heat conduction
• Engineered oil grooves and distribution channels for enhanced lubrication under extreme loads
• No cosmetic tin flash coating to prevent plate migration and bearing distortion under high heat and loading

Technical Specifications:

• Maximum shaft size: 2.126" (54mm)
• Maximum tunnel size: 2.271" (57.696mm)
• Vertical oil clearance range: 0.0018" to 0.0034" (0.046mm to 0.087mm)
• Wall thickness at crown: 0.072" (1.818mm)
• Overall bearing length: 1.005" (25.52mm)

ACL Race Series bearings are specifically designed for engine tuning and performance upgrades where superior bearing capacity and reliability are essential. The HX variant's increased oil clearance makes it ideal for high-revving race engines and applications with increased bearing temperatures.
