Product Details

The ACL Bearings 5M590P-10 is a precision-engineered main bearing set designed for Small Block Ford 289-302 cubic inch engines from 1962 to 1998. This set features a 0.010 inch undersize specification, making it ideal for use with reground crankshafts during engine rebuilds and performance builds.

Key Features:

  • Multi-layered tri-metal copper alloy construction provides high strength and excellent seizure resistance
  • Manufactured to exact tolerances for reliable fit and consistent bearing clearances
  • 1/2 groove design optimizes bearing load carrying surface area and oil flow
  • Hardened steel backing improves bearing support and retention in the housing
  • Increased crush helps lock bearings securely in place
  • Enlarged inner diameter chamfers accommodate larger fillet radius on performance crankshafts
  • Tight, consistent wall tolerances help maintain proper oil clearances

ACL's precision manufacturing and quality control processes ensure these bearings deliver the dependability required for both street performance and racing applications. The tri-metal construction blends material characteristics to provide durability under demanding operating conditions while maintaining proper oil film thickness.

Great experience with autoplicity. Fast shipping. Ordered on 5/31 got bed cover on 6/2. Fit truck perfect.

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!

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!

the shipping charges were high, but still cheaper than any place else with free shipping!

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