Product Details

The ACL Bearings 5M8353H-.25 Race Series main bearings are engineered for high-performance and racing applications where reliability under extreme conditions is critical. These main bearings feature a 0.25mm undersize specification, designed for crankshafts that have been machined or require precise clearance adjustments.

Key Features:

  • Race Series construction for enhanced durability in high-RPM applications
  • 0.25mm undersize for precision fitment on machined crankshafts
  • Advanced tri-metal bearing material with improved load capacity
  • Optimized oil clearances for maximum protection and performance
  • Manufactured to strict tolerances for consistent quality
  • Suitable for street performance, road racing, and drag racing builds

ACL Race Series bearings are a trusted choice among engine builders and performance enthusiasts who demand superior bearing technology. The undersize specification allows for proper clearance restoration when crankshaft journals have been machined to remove wear or damage.

so far this has been an excellent experience... we will see how the shipping, arrival, accuracy and quality when the parts show up.

Second time customer of Autoplicity: Ordered Husky Liners Weatherbeater Floor mats for a 2012 Toyota Tundra, Called in this morning to verify availability, call answered on second ring, great service placed the order immediately. Haven't even received the product yet but the service has been so outstanding had to let everyone know this company is for real. Best pricing online, wont buy products anywhere else.<br><br>Justin Myers
