ACL Bearings 5M1743H-20 Race Series Main Bearing Set Ford Oversize - 2.3L 020

The ACL Bearings 5M1743H-20 Race Series main bearing set is engineered for extreme performance applications in Ford 2.3L (2300cc) engines with small journal crankshafts. This .020" oversize bearing set is specifically designed for engines that have been machined to accommodate oversized bearings, providing a precision fit for rebuilt or reconditioned crankshafts.

Race-Proven Performance Features:

• Tri-metal construction with high-strength overlay plate and reduced thickness for superior fatigue resistance
• Designed to withstand high RPM conditions and extreme cylinder pressures in racing applications
• Increased bearing crush for improved retention and heat transfer
• Increased eccentricity to compensate for bore distortion at high RPM and assist in hydrodynamic oil film formation
• 3/4 grooved design optimizes bearing load carrying surface area and oil flow to connecting rod bearings
• Elimination of flash plating on bearing backs improves heat dissipation and grip in housing bores
• Hardened steel backing provides exceptional support for the bearing lining

ACL Race Series bearings are trusted by engine builders and racers worldwide, from drift racing to NASCAR competitions. These bearings deliver the unique combination of metallurgy, design, and engineering required for extreme endurance under harsh racing conditions where lesser bearings fail. Compatible with Ford 2.3L engines including Pinto, Mustang, and Ranger applications with small main journal crankshafts.
