ACL Bearings 5M1704-.75 Main Bearing Set Undersize - 75mm

ACL Bearings produces one of the largest aftermarket ranges of engine bearings with a global reputation for robust metallurgy, quality, precision, innovation and performance. For over 70 years, precision engine bearings have been manufactured in Tasmania, Australia, with ACL serving as a major OEM supplier to the Australian and international automotive industry.

Key Features:

• Tri-Metal construction combines the strength of a copper-lead alloy layer with steel backing and an electroplated babbitt metal overlay for critical surface characteristics of slipperiness and conformability
• Improved eccentricity to compensate for bore distortion at high-speed operation and assist in hydrodynamic oil film formation
• Improved bearing retention from higher radial contact pressure that locks the bearing into the housing and provides more effective heat dissipation through improved thermal transfer
• Engineered to provide dependability under higher RPM conditions and perform to exacting race standards
• .75mm undersize specification for reground crankshaft journals

ACL bearings feature a dark tarnished coloration which can vary from dark black, blue, or brown colors as a result of the electroplating process, with copper in the electroplated overlay composition tarnishing to these characteristic colors. This main bearing set is precision-manufactured to deliver reliable performance in demanding applications.
