Product Details

The ACL Bearings 4B1155-.25 is a precision-engineered connecting rod bearing set designed for high-performance engine builds and rebuilds. This set features a 0.25mm (0.010") undersize specification, making it ideal for crankshaft journals that have been machined undersize during reconditioning or performance machining operations.

Key Features:

  • Precision 0.25mm undersize specification for machined crankshafts
  • High-quality tri-metal construction for enhanced durability and wear resistance
  • Engineered bearing geometry optimizes oil film thickness and load distribution
  • Manufactured to strict tolerances for proper clearances and reliability
  • Complete connecting rod bearing set for multiple cylinders
  • Suitable for performance, racing, and professional engine rebuilding applications

ACL Bearings are manufactured using advanced materials and processes to deliver consistent quality and performance. The undersize design compensates for material removed during crankshaft grinding, restoring proper bearing-to-journal clearances. This bearing set provides the foundation for a durable, high-performance engine build capable of withstanding demanding operating conditions.

Good store to deal with.<br><br>Will purchase from them again.

I was very surprised that even with shipping, I saved 40% over the exact same item at a local auto store. They shipped the next business day and I am expecting to receive within 1 week of placing the order.<br>Autoplicity's website is easy to navigate and the selection and prices are top notch. I will be ordering from here again!

I ordered a Volant cold air intake for my truck,, really fast shipping and product got home without a scratch,,great website,,this is my first time shopping at autoplicity and im definatley going to shop there again.

Autoplicity is my number one choice for auto parts.

Same day shipping. 20 Dollars cheaper than everywhere else!

Amazing prices and amazing shipping speed! Best all around. Will be ordering more soon!
