ACL Bearings 8B743P-20 Performance Connecting Rod Bearing Set Undersize - 0.020

The ACL Bearings 8B743P-20 is a high-performance connecting rod bearing set designed for demanding engine builds. This set features 0.020" undersize dimensions for use with reground crankshafts, providing proper bearing clearances on journal surfaces that have been machined undersize.

ACL Race Series Technology:

• Trimetal construction with hardened steel backing for superior strength and retention
• High-strength overlay with optimized thickness for improved fatigue resistance
• Enhanced bearing crush ensures positive retention and prevents bearing spin
• Improved heat dissipation through better thermal transfer to the connecting rod
• Chamfered bearing edges accommodate larger fillet radii on performance crankshafts
• Precision-engineered oil grooves promote hydrodynamic oil film formation

Key Features:

• 0.020" undersize for reground crankshaft journals
• Race-proven durability for high-performance street and track applications
• State-of-the-art metallurgy withstands extreme loads and temperatures
• Dark tarnished appearance from copper-based overlay (normal characteristic)
• Manufactured to exacting tolerances for consistent bearing clearances

ACL Race Series bearings are trusted by engine builders worldwide for their exceptional quality and performance. These bearings deliver reliable operation in high-horsepower builds where standard bearings cannot perform. Complete connecting rod bearing set included.
