Product Details

The ACL Bearings 4B1891-020 is a precision-engineered connecting rod bearing set designed for 0.020" oversize crankshaft journals. This high-quality bearing set provides reliable performance for classic British Motor Corporation (BMC) engines found in MGA, early MGB (through 1964), and Austin A50, A55, and A60 vehicles.

Key Features:

  • Tri-metal construction for superior fatigue resistance and durability
  • Hardened steel backing provides improved support and bearing retention
  • Precision-machined to exacting tolerances for optimal clearances
  • 0.020" oversize for use with reground crankshafts
  • Enhanced heat transfer characteristics for cooler operation
  • Manufactured by ACL, a trusted name in performance and replacement engine bearings

ACL connecting rod bearings are engineered with advanced metallurgy and manufacturing processes to deliver consistent performance in both street and performance applications. The oversize design allows for proper bearing clearances when installing on a crankshaft that has been machined to restore journal dimensions.

Definitely the best price that I found for the part that I needed! Customer service was helpful and I got the piece FAST! Thank you so much!

First off, I LOVE my new shipments! These guys had everything at super low prices, and the shipping was phenomenally fast. It's all working great, and imm definitely buying from these guys again.

Seller had the best price online for the item I wanted! Responded to emails within 24 hours as stated, and sent me my tracking info as soon as part shipped. Thanks Autoplicity!

Ordered a Trac-Bar from Autoplicity, and didn't have any problems. WILL be back!

Product (Dee-Zee nerf bars) was exactly as advertised. Buying experience was great. I did contact customer service via email to find out the shipping information. They were very helpful and replied within a few hours.

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.
