ACL Bearings 4B603H-10 Race Series Connecting Rod Bearings Ford Kent Lotus .010 Oversize

The ACL Bearings 4B603H-10 Race Series Connecting Rod Bearings deliver race-tested durability and precision engineering with advanced trimetal design featuring a high-strength overlay plate with reduced thickness for improved fatigue resistance, backed by hardened steel for enhanced support and retention under extreme conditions. This .010" oversize bearing set is specifically designed for Ford Kent and Lotus applications including 1098cc-1598cc Kent engines, Lotus Twin Cam, and Ford Pinto/Fiesta variants.

Key Performance Features:

• Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing
• Elimination of flash plating on the back of the bearings to improve heat transfer and maximize grip between bearings and housing
• Increased eccentricity to compensate for bore distortion at high RPM and assist in the formation of hydrodynamic oil films
• Tight consistent wall tolerances to help maintain consistent clearances
• Enlarged ID chamfers on bearing edges to accommodate large fillet radius on performance crankshafts

This connecting rod bearing set contains 8 half shells, with 4 of the shells designed with oiling squirter holes as per the original Ford design, completing one 4-cylinder engine. ACL Race Series performance engine bearings are recognized as a premier brand throughout the motorsports world, with the unique combination of design, metallurgy, and engineering providing Race Series bearings with the endurance and capability to perform where others cannot.
