Product Details

The ACL Bearings 4B8331-1.00 is a precision-engineered connecting rod bearing set designed for Mazda B-series inline 4-cylinder engines, including B1, B3, B5, and Z5-DE variants ranging from 1.1L to 1.6L displacement. This bearing set features 1.00mm (.040 inch) undersize dimensions, making it ideal for rebuilt or reground crankshafts that require precise clearance adjustment.

Key Features:

  • Hardened steel backing provides superior strength and support for the bearing lining
  • Multi-layer construction with copper-lead-tin lining for excellent fatigue resistance
  • Lead-tin-copper overlay provides seizure resistance and low friction properties
  • Nickel barrier layer prevents copper migration and extends bearing life
  • Precision manufactured to OEM specifications for proper fit and performance
  • 1.00mm undersize accommodates crankshaft regrinding and wear compensation

ACL Bearings is recognized throughout the automotive industry for producing high-quality engine bearings that meet or exceed OEM standards. Each bearing in this set is manufactured with tight tolerances to ensure proper oil clearance, load distribution, and durability in demanding engine applications.

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.

Like the simplicity so far. Ordered my product on Sunday shipped out Tuesday so we'll see how fast and efficient shipping is.

Autoplicity had the lowest price I found on the product I wanted. Also, the item was shipped very quickly. I received 2 days after I purchased it. Great service!

Great Place to shop for Auto Parts Very Fast shipping

I am extremely happy with Autoplicity from start to finish! They had the best prices online on Hawk Performance pads and were shipped the day I ordered. They were at my door step within two days of me ordering them! You can't beat that anywhere. Cheaper and faster, it truely dosen't get any better than that.

Ordered a Thule hitch and was a little skeptical because I hadn't heard of this company. I was pleasantly surprised by the quickness of response when I ordered, I received an email immediately, and the order arrived just 2 days after it was ordered. This company goes to the top of my list.

Comparable pricing, fast trackable shipping.

Great prices, and much faster delivery than expected. They "over-delivered" on what they said they'd do. Will definitely use them again!

Autoplicity gave me no hassles ever, the price dropped on the product I ordered and I just contacted BuySafe and received the difference quickly. Order was shipped same day. I will buy them over and over again! Thank you Autoplicity.
