Product Details

The ACL Bearings 4M8147-.75 is a precision-engineered main bearing set designed for 4-cylinder engine applications requiring 0.75mm (0.030") undersize bearings. This bearing set is specifically manufactured for use with reground crankshafts where the main journals have been machined down 0.75mm from standard size to restore proper clearances and ensure optimal engine performance.

Key Features:

  • 0.75mm (0.030") undersize specification for reground crankshafts
  • Precision tolerance construction for consistent oil clearances
  • High-quality bearing material for durability and wear resistance
  • Engineered to OEM specifications for reliable performance
  • Complete main bearing set for all main journal positions

ACL Bearings are manufactured using advanced metallurgy and engineering processes to deliver the performance characteristics required in both OEM replacement and performance applications. These undersized bearings allow engine rebuilders to properly match bearing dimensions to reground crankshaft journals, maintaining the critical oil clearances necessary for proper lubrication and longevity.

I was skeptical about Autoplicity since I hadn't heard of them before, and that their price was 12% lower than anyplace else I could find. Plus, I couldn't even find a store around here that carried the X-jack. Plus I got it delivered right This my door fast. You people are Excellent!

Great

The best price found on the net for an Airtex fuel pump. Fast shipping via UPS. Received 08/09/2012<br><br>Autoplicity is now in my favorites. Order Number: <br>Ray J.

Excellent business and a pleasure to deal with. Lowest prices on the net and great communication between the business and myself. Will purchase from again!

Very easy to order, updated regularly on status, great pricing and product
