ACL Bearings 5M1117H-01 Race Series Main Bearing Set Ford 2.3L 2300 .001" Oversize

The ACL Bearings 5M1117H-01 Race Series main bearing set is engineered for extreme endurance under harsh racing conditions. This .001" oversize bearing set is designed specifically for Ford 2300 single spark plug engines, providing the precision and durability demanded by high-performance builds.

Advanced Tri-Metal Construction:

• High strength overlay plate with reduced thickness for improved fatigue properties
• Hardened steel backs on rod bearings to improve support and assist with bearing retention
• Elimination of flash plating on bearing backs to improve heat transfer and maximize grip
• Increased eccentricity to compensate for bore distortion at high RPM
• 3/4 grooved design to optimize bearing load carrying surface area and oil flow

Race-Proven Performance:

ACL Race Series bearings are standard components in race engines that have set records and won championships from Mexico to Bonneville, competing in sport compact drift racing, NASCAR, IHRA, and NHRA competitions. ACL is an engine builder's top choice for quality and consistency, trusted as an Original Equipment supplier.

When running high RPMs and big boost, fatigue, stress wear, and failure are factors eliminated by ACL's advanced metallurgy. The special coating process helps prevent premature bearing failures and expensive engine damage. This .001" oversize set provides additional clearance for performance applications requiring precise oil clearance control.
