Product Details

ACL Race Series main bearings are engineered for high-performance and racing applications where durability and precision are critical. These .025" undersize main bearings are designed for engines that have been machined undersize during rebuilds or performance builds.

Key Features:

  • Race Series construction for extreme performance applications
  • .025" undersize for machined crankshafts
  • High-strength tri-metal construction with enhanced load capacity
  • Precision manufacturing ensures optimal oil clearances
  • Designed to withstand high RPM and increased cylinder pressures
  • Superior fatigue resistance for extended service life

ACL Race Series bearings feature advanced materials and coatings specifically developed for racing engines, providing the reliability needed in competition and high-performance street applications. The .025" undersize dimension allows for proper bearing crush and oil clearance when crankshaft journals have been turned undersize.

Great company..Great communication..Fast shipping. A+++++++++++++++.<br>Will do business again.

My ARB 50qt fridge/freezer arrived quickly and it was way cheaper than anywhere else. I was a little leery only because of that. However, I received the fridge and saved about $65 over even Amazon. No problems.

Your website is good but I wish the pictures you show for the items was correct so your customer can feel sure about their purchase so I hope what I just bought is what I think it is.

Pricing was good and customer service quick to respond.
