ACL Bearings 8B1633P-20 Connecting Rod Bearing Set Undersize - 0.020

The ACL Bearings 8B1633P-20 is a precision-engineered connecting rod bearing set designed specifically for Ford/Navistar V8 444 (7.3L) Powerstroke diesel engines from 1994 and newer. This set features 0.020" undersize dimensions for use with reground crankshafts during engine rebuilds.

Advanced Trimetal Construction:

• High-strength overlay plate with reduced thickness for improved fatigue resistance under high-load conditions
• Hardened steel backing on all rod bearings to enhance support of the bearing lining and assist with retention in the housing
• Elimination of flash plating on bearing backs to improve heat transfer and maximize grip between bearings and housing

Performance Features:

• Increased eccentricity to compensate for bore distortion at high RPM and assist in hydrodynamic oil film formation
• Tight, consistent wall tolerances to help maintain proper bearing clearances throughout the engine rebuild process
• Enlarged ID chamfers on bearing edges to accommodate large fillet radius on performance crankshafts
• Designed to withstand the demanding conditions of diesel engine operation

ACL Race Series bearings deliver the durability and precision needed for both street and performance diesel applications, making them an ideal choice for rebuilding your 7.3L Powerstroke engine.
