Product Details

The ACL Bearings 4B1776-.25 is a precision-engineered connecting rod bearing set designed for high-performance and racing engine applications. This set features a 0.25mm (0.010") undersize specification, making it ideal for engines that have had their crankshaft journals machined or polished during rebuild processes.

Key Features:

  • Premium tri-metal construction for superior durability and wear resistance
  • 0.25mm undersize specification for machined crankshafts
  • Precision manufacturing to tight tolerances for optimal oil clearance
  • Enhanced fatigue strength for high-RPM and high-load applications
  • Compatible with both street performance and racing engines
  • Complete connecting rod bearing set for multi-cylinder engines

ACL Race Series bearings are manufactured using advanced metallurgy and coating technologies to provide exceptional protection under extreme operating conditions. The undersize design allows engine builders to restore proper bearing clearances when crankshaft journals have been refinished below standard dimensions.

Great prices and timely shipping. They had the best price of all of the online stores I checked for my Superchips programmer. Thanks very much Autoplicity!

Amazon payment integration is great! Plus great prices!

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
