Key Features:

  • 0.75mm undersize thickness for reground crankshafts
  • ACL's proven Aluglide or Duraglide metallurgy for superior strength and wear resistance
  • Steel backing provides excellent support and heat transfer
  • Proprietary composition of aluminum, tin, and silicon for exceptional anti-seizure and anti-wear properties
  • Precision manufactured to OEM specifications for reliable fitment

ACL Bearings has been manufacturing high-quality engine bearings for over 70 years, supplying both original equipment manufacturers and the performance aftermarket. When rebuilding engines with machined crankshafts, selecting the correct undersize bearing is critical for proper clearances and long-term durability. This bearing set ensures proper oil film thickness and load-carrying capacity for rebuilt engines.

Note: This part has been superseded by 4M8063A-.75. Please verify the current part number when ordering to ensure you receive the latest version with any manufacturing improvements.
