Product Details

The ACL Bearings 4B1647A-.75 is a precision-engineered connecting rod bearing set designed for engines with reground crankshafts. This bearing features a 0.75mm (approximately .030") undersize specification, making it ideal for crankshafts that have been machined down to restore proper journal dimensions.

Key Features:

  • 0.75mm (.030") undersize for reground crankshaft journals
  • Precision tri-metal construction for enhanced durability and wear resistance
  • Engineered to meet or exceed OEM specifications
  • Copper-lead alloy bearing surface for optimal lubrication
  • Steel backing provides superior strength and support
  • Manufactured with tight tolerances for proper oil clearance

ACL bearings are trusted by professional engine builders worldwide for their consistent quality and performance. The undersize design compensates for material removed during crankshaft grinding, ensuring proper bearing crush and oil clearance when installed. Always verify crankshaft journal measurements and check bearing clearances with plastigage before final assembly.

Great price for the item, almost half off. Good website for auto parts

I did a google search for the part I was looking for. In this case a Borgeson steering box for my Dodge 2500. Autoplicity had the best price. I ordered it and it arrived shortly thereafter, no problems, no hassles. Great service, thanks<br><br>Brendan
