Product Details

The ACL Bearings 8B831AO/S2-40 is a precision-engineered connecting rod bearing set designed for crankshafts that have been ground 0.040" undersize. This Aluglide series bearing features an oversized outer diameter (OD) to accommodate connecting rod housings that have been honed or bored oversize, making it ideal for engine rebuilds where bore correction is necessary.

Key Features:

  • Bi-metal Aluglide construction with proprietary aluminum, tin, and silicon alloy
  • Steel backing provides exceptional wear resistance and outstanding strength
  • Oversized OD design (S2 designation) for oversized bearing housings
  • 0.040" undersize for reground crankshaft journals
  • Excellent load-carrying characteristics for reliable performance
  • Precision-manufactured to exacting tolerances for proper oil clearance

ACL Aluglide bearings are engineered to meet OEM specifications while providing enhanced durability for performance rebuilds. The oversized outer diameter compensates for material removed during housing reconditioning, ensuring proper crush and heat transfer. These bearings are designed for automotive gas engines requiring exact replacement dimensions for professional engine rebuilding applications.

Excellent selection, great prices, and fast shipping. I am very satisfied.

Thanks!

Product was as described, shipping was fast, and communication was excellent. Plus I saved $$. Thanks Autoplicity! I'll be a repeat buyer and referral source.

After seeing that Autoplicity was in good standing with the BBB and had favourable reviews reported elsewhere I placed an order on a Sunday evening. On Monday morning I already had a confirmation email and order number. On Tuesday I was notified that my order had shipped. Their price of $477 on the part I ordered was about $30 cheaper than Summit Racing, who I usually do business with, and the cost of shipping and handling was only a few dollars more. I haven't recieved the part yet but have no reason to think I won't be totally satisfied with the transaction.

Unbelievable price!Fast shipping and a great product.Thank You.

Best price around, very fast shipping and great service! I will buy from them again!
