Product Details

The ACL Race Series main bearings are engineered for high-performance engine builds requiring superior durability and precision. These bearings feature ACL's advanced tri-metal construction with a steel backing, high-strength copper-lead alloy intermediate layer, and a specialized overlay designed to withstand extreme loads and temperatures in racing applications.

Key Features:

  • Race Series construction for maximum strength and durability
  • 0.25mm oversize for machined crankshafts requiring slight oversize bearings
  • Tri-metal design with optimized material composition
  • Enhanced oil clearance specifications for high-RPM operation
  • Precision manufacturing to tight tolerances for consistent fitment
  • Suitable for naturally aspirated and forced induction applications

ACL Race Series bearings are the choice of professional engine builders and serious enthusiasts who demand reliability under the most demanding conditions. The 0.25mm oversize allows for proper clearances when crankshafts have been machined to restore journal surfaces.

The time recieved and the product was good but the product didn't work with my car as advertised because I ha e such a specific fuel pump relay.

Easy to shop. Now waiting for product to ship and see about install.

Recieved what was ordered. I looked for this specific part for a few years and finally found for an exceptional price here.

Product was great quality and fit perfect on my 2005 Ford f150.

Great product, fast shipping!!

Very helpful

Unbeleively fast shipping. I ordered on a Tuesday night, and it was delivered to my door by Thursday. Plus, the item was the cheapest with shipping on the web! I will most certainly be doing business with them again!

Nice website, easy to use.

Great selection and easy checkout! The only thing is I didnt get an email confirmation as soon as I order which made me wonder is the transaction went through. I did get an email once the items were shipped though.
