ACL Bearings 8B818H-STD Race Series Connecting Rod Bearing - Set

The ACL Bearings 8B818H-STD is a high-performance connecting rod bearing set engineered for Ford big block V8 engines including the 370, 429, and 460 cubic inch applications. Part of the acclaimed Race Series line, these tri-metal bearings are designed to withstand the extreme demands of high-RPM performance engines and motorsports applications.

Key Features:

• High-strength overlay plate with reduced thickness for improved fatigue properties
• Hardened steel backing on all rod bearings to improve support and assist with bearing retention in the housing
• Increased crush for improved bearing retention under high-stress conditions
• Elimination of flash plating on bearing backs to improve heat transfer and maximize grip between bearings and housing
• Increased eccentricity to compensate for bore distortion at high RPM and assist in hydrodynamic oil film formation
• Tight consistent wall tolerances to help maintain precise clearances
• Enlarged ID chamfers on bearing edges to accommodate large fillet radius on performance crankshafts
• Standard size bearing set

ACL Race Series bearings feature F781 tri-metal construction combining copper, lead, and tin for exceptional durability and load-carrying capacity. The unique combination of design, metallurgy, and precision engineering delivers the endurance required for everything from high-performance street engines to professional racing applications. These bearings are trusted by engine builders worldwide and are found in championship-winning engines across multiple motorsports disciplines.
