ACL Bearings 1B1280-1.00 Conrod Bearing Set Undersize - 1.00mm

The ACL Bearings 1B1280-1.00 is a complete connecting rod (conrod) bearing set designed for engines with crankshafts that have been reground to a 1.00mm undersize. Engineered to ACL's exacting standards, this set delivers reliable performance for both daily-driven and performance-built engines.

Key Features:

• Tri-metal copper-lead construction using ACL's Duraglide F780 heavy-duty material for superior load capacity and wear resistance
• 1.00mm undersize ? engineered for use with crankshafts reground 1.00mm under standard journal diameter
• High-strength steel backing for improved bearing retention and structural rigidity under load
• Increased crush for higher radial contact pressure, improving retention and heat dissipation
• Tight production tolerances manufactured to maintain precise oil clearances for optimal hydrodynamic film formation
• Enlarged chamfers to accommodate larger fillet radii common on performance and reground crankshafts
• Sold as a complete conrod bearing set (big end bearings for all cylinders)

ACL has been producing engine bearings since 1922 and is a trusted name among professional engine builders worldwide. The 1B1280-1.00 conrod bearing set is an ideal choice for engine rebuilds requiring undersize rod bearings after crankshaft reconditioning.
