ACL Bearings 8B818P-20 Connecting Rod Bearing Set Oversize Ford - 20mm 370 429 460

The ACL Bearings 8B818P-20 is a precision-engineered trimetal connecting rod bearing set designed specifically for Ford big block 370, 429, and 460 cubic inch V8 engines produced from 1968 to 1998. This bearing set features a .20mm oversize dimension for use with reground crankshafts or worn connecting rod bores that have been machined to accommodate the increased bearing thickness.

Trimetal Construction:

These bearings utilize ACL's proven trimetal design featuring a copper-lead-tin bearing surface bonded to a hardened steel backing. This construction provides superior durability, exceptional load-carrying capacity, and enhanced fatigue resistance compared to bimetal alternatives. The trimetal composition is specifically engineered for the high loads and demanding conditions found in larger displacement V8 engines.

Key Features:

• Trimetal bearing material with copper-lead-tin overlay for maximum durability
• .20mm oversize for machined crankshafts or connecting rods
• Hardened steel backing provides excellent support and heat transfer
• Precision-engineered oil grooves for optimal lubrication
• Complete set includes bearings for all connecting rods
• Ideal for street performance, muscle car rebuilds, and recreational applications

ACL Bearings manufactures these components using precision engineering with minimal tolerances to ensure reliable performance and proper fitment. While not quite reaching the extreme performance capacity of ACL's Race Series bearings, these trimetal bearings offer an excellent balance of durability and performance for street and moderate performance applications.
