Product Details

The ACL Bearings 6B663P-20 is a high-performance connecting rod bearing set designed for precision engine builds requiring 0.020" undersize bearings. ACL bearings are manufactured in Tasmania, Australia, and have been trusted by engine builders worldwide for over 70 years in both OEM and performance applications.

Key Features:

  • 0.020" undersize for reground crankshafts
  • Tri-metal copper-lead construction for superior strength and fatigue resistance
  • Hardened steel backing provides improved support and bearing retention
  • Precision wall thickness tolerances ensure consistent oil clearances
  • Enhanced heat dissipation through optimized thermal transfer design
  • Increased crush factor for superior bearing retention in housing
  • Enlarged ID chamfers accommodate large fillet radii on performance crankshafts
  • ISO certified manufacturing processes ensure consistent quality

ACL connecting rod bearings feature advanced metallurgy with improvements in material composition, dynamic thickness, heat conduction, and oil distribution. These bearings are suitable for street performance, racing applications, and engine rebuilds where precision and reliability are essential. The tri-metal construction delivers the durability needed to withstand high RPM conditions and demanding operating environments.

I was a first time customer, but will definitely visit Autoplicity.com again! Great prices, and fast shipping! Thanks!!

Great Price for the struts i ordered!

Fantastic service and fast shipping! Lowest price on the net for the CAI that I bought!<br><br>This is my new "Go To" website for parts.<br><br>Thanks!

I bought an Edge Evolution CS tuner for my 05 Avalanche at a great price, a lot cheaper than any other place I looked. Delivery time was amazing it tooked two days from the time it was processed and it was over the Christmas holiday and it still made it to my front door in less than a week with regular ground shipping. Customer support is awesome and fast at answering any and every question you have and remedying any problem. Great site and great service. Will definitely recommend to others and use again in the future for all my automotive needs. Thanks Autoplicity.

By the time you add in shipping, even the "Rock" can't compare! Thanks!

Looked everywhere for a good price on Warn locking hubs, they were the best price around. Shipped right away.

Best price on a holley carburetor online. I unusually use summit but even the shipping price is less, no handling fees either. I am hearing great things about the shipping so I am hopeful the 69 javelin is back on the road this week! If it works out I will tell all my motor head friends about this site!

The correct product that I ordered, and easy to find through there web site.thanks
