Description

The ACL Race series engine bearing set is a high-performance solution for enthusiasts building 3.0L 2JZGE and 2JZGTE engines. Engineered for extreme endurance, these tri-metal bearings (material F780) provide superior load-carrying capacity compared to standard components, making them suitable for engines subjected to high RPMs, boost, and performance upgrades. Featuring increased eccentricity, these bearings improve shape adaptation to compensate for bore distortion during high-speed operation. The main bearings (7M8103H) are manufactured for precise fitment within the specified shaft size range of 2.4403 to 2.441 inches. Designed as a direct-fit upgrade for platforms like the Toyota Supra (1993-1998) and Lexus SC300 (1991-2000), these bearings ensure reliable oil film maintenance and structural integrity under demanding performance loads. Proper sizing should be verified during engine assembly to match the specific requirements of your crankshaft and block clearances.
