Product Details

The QA1 AIB4 is an AIB Series spherical bearing featuring a 1/4 in. (0.250 in.) inner bore diameter, built for performance suspension, racing, and industrial linkage applications. AIB and AIB-T Series bearings are engineered from alloy/chromoly steel to deliver superior wear resistance compared to traditional carbon steel alternatives.

Key Features:

  • Ball: 52100 Bearing Steel — Heat Treated, Precision Ground, and Hard Chrome Plated for exceptional hardness and smooth articulation
  • Race: Alloy/Chromoly Steel — Heat Treated with a protective corrosion-resistant coating and oil coating from the manufacturer
  • Bore Size: 1/4 in. (0.250 in.) inner diameter
  • Available with optional PTFE liner (AIB-T Series) for self-lubricating, reduced-maintenance operation
  • Precision ground construction ensures accurate fitment and consistent performance

QA1's AIB Series spherical bearings are a trusted choice for circle track racing, drag racing, street rod builds, and performance suspension systems where reliable motion control and long service life are required.

So far order placement was easy. Used pay with Amazon.

This site is awsome! excellent customer service, lowest rate, Fast shipping!<br><br>I will save this site for my bookmark! %100 must check auto store site.

I got a cargo box from autoplicity. As far as online purchases go to delivery, everything went perfectly. The only comment I have for Autoplicity would be to send out a confirmation email when the purchase is first made. The first communication wasn't until 3 days after I made the purchase.

Best price I could find for the brand new name brand product I ordered. Fast shipping as well.
