Product Details

The ACL Bearings 8B663P-40 is a high-performance connecting rod bearing set engineered for demanding automotive applications. ACL Race Series bearings feature advanced metallurgy and precision manufacturing to deliver superior durability and reliability under high-stress conditions.

Key Features:

  • Tri-metal construction with steel backing, copper-lead intermediate layer, and polymer overlay
  • .040" (1.0mm) undersize for crankshaft journal regrinding applications
  • Precision bore geometry for optimal oil clearance and load distribution
  • Enhanced fatigue resistance for high-performance and racing applications
  • Engineered bearing profiles reduce friction and improve oil film retention
  • Strict quality control ensures consistent dimensional accuracy

ACL bearings are designed to meet or exceed OEM specifications while providing the enhanced durability required for modified engines, forced induction, and racing applications. The .040" undersize designation makes this bearing set ideal for engines with reground crankshafts or worn journals requiring machine work.

Great Price on products and Shipping

Ordering was very easy and product was delivered within a week. I ordered a battery and it was received in good condition and works. I would recommend autoplicity to others.

Love my new Eibach Springs. Look & Feel Great! Fast Shipping and awesome customer service!

This is our second order from Autoplicity. The first one didn't go so well due to a mix up with the Sparco seat pricing. Though I was starting to question our decision to order from them after several emails and phone calls and online chats, they came through in the end. These guys earned our second order by honoring the price they had listed and then calling to follow up when our race seat was shipped. Since this group was able turn our bad experience into a positive one we made our second order and, so far, it looks like they are again getting us what we want at the best price we can find. We are happy to recommend Autoplicty and plan on using them for future orders. There is one specific thing we would recommend, change the quality and volume of the hold music on the 800 #. It sounded like we were calling a 1970's van with a blown Jensen stereo turned all the way up,...

Shipped very quickly and had the best price I could find!

Great prices on most things. Ordered on a sunday and they processed and shipped the order the next day.

This was my first order with Autoplicity and I am very happy. They had the lowest price on-line that I found. Communication was great and shipping was very fast. I ordered late on Thursday and it was at my house the following Tuesday, and I didn't pay for rush shipping. I got exactly what I expected. Will do business with these guys again.
