Product Details

ACL Race Series main bearings are engineered for high-performance and racing applications where durability and precision are critical. The 5M1913H-.25 designation indicates these are undersize bearings, specifically 0.25mm (0.010") undersize, designed for use with crankshafts that have been machined to remove wear or damage.

Key Features:

  • Race Series construction for enhanced durability under extreme loads and high RPM conditions
  • Precision-engineered tri-metal design with steel backing for superior strength
  • Advanced bearing material optimized for high-performance engines
  • 0.25mm undersize for use with reground crankshafts
  • Tighter tolerances than standard bearings for improved oil film consistency
  • Designed to withstand the demanding conditions of racing and performance applications

ACL Race Series bearings are a popular choice among engine builders and racers who demand reliable performance under the most demanding conditions. These main bearings provide the durability and precision needed for high-output engines, whether for track use, competition, or high-performance street applications.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Great site has alot of items in stock. Shipped promptly! Can't wait to do buisiness again.

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
