Product Details

The ACL Bearings 4B1623PO/S2-.25 is a precision-engineered connecting rod bearing set designed for high-performance engine applications. This bearing set features ACL's Performance Series construction with advanced tri-metal technology for superior durability and load capacity under extreme operating conditions.

Key Features:

  • Undersize specification: .25mm (0.010") for precision crankshaft grinding and optimal clearance
  • Tri-metal construction with steel backing, copper-lead intermediate layer, and polymer coating
  • Extra oil groove (PO) design for enhanced lubrication in high-RPM applications
  • S2 polymer overlay for improved wear resistance and seizure protection
  • Precision tolerances for consistent bearing clearances and reduced friction
  • Engineered for racing, performance, and heavy-duty applications

ACL's Performance Series bearings are manufactured to exacting standards and provide excellent fatigue resistance, embeddability, and compatibility with modern synthetic oils. The undersize specification allows engine builders to restore proper bearing clearances after crankshaft machining operations.

Looked around online everywhere for my spark plug set. Autoplicity had what I wanted at the lowest price. Thanks guys!

Easy payments through Amazon.

Fast, Professional and great prices.

Best price for an expired item around, though more options in shipping would be appreciated. Ordered saturday night and item shipped tuesday morning, saved about 30% off of the originally planned purchase price. Definitely will use them again in the future.

Needed a pair of brake pads all the way around for my car, Autoplicity had the exact parts in stock and also the best price. Shipped same day. Very Pleased. Order # 19227
