Product Details

The ACL Race Series main bearings are high-performance engine bearings designed for racing and high-output applications. These main bearings feature ACL's advanced tri-metal construction with a steel backing, copper-lead intermediate layer, and proprietary polymer coating for superior durability and friction reduction under extreme conditions.

Key Features:

  • Race Series construction for maximum performance and reliability
  • -.025mm (undersized) specification for precision fitment on machined crankshafts
  • Tri-metal design with steel backing for superior strength
  • Proprietary polymer top coating reduces friction and improves oil retention
  • Engineered for high RPM and high load applications
  • Enhanced fatigue resistance for extended service life
  • Precision manufactured to tight tolerances for optimal clearances

ACL Race Series bearings are the choice of professional engine builders and racing teams worldwide. The -.025mm undersize dimension allows for proper bearing clearance when crankshaft journals have been ground or machined for repair or performance applications.

Quick and easy to use

Wow!! I came across Autoplicity while searching for a fuel pump for my Trans-Am. Not only did they have the cheapest price for the part, but they also had extremely reasonable shipping cost. Most websites claim to have free shipping but it seemed the cost of shipping was added to the cost of their part. Then I find out my order was processed and shipped within one business day!! I'll definately be bookmarking Autoplicity's home page!! Thanks!!

Is been a great experience, just hope nothing goes wrong when I receive my part

The item arrived fast and in good condition. There however seems to be a glitch with the scale the first time we weighed something. After we shut it off and then back on it seemed to be OK.

I ordered a Grant 1103 Steering Wheel, Order Number: 16767. Great prices, quick shipping, good customer service, an all around deal. Thank you.

The part I purchased had the lowest price I could find online anywhere.. Simple transaction and fast shipping.. Ordered on a Monday and delivered by Friday..

It has been a smooth and easy process. I would definitely use them again.

Great prices and fast delivery.

best prices around !! Shipping was FAST !
