ACL Bearings are a top choice for engine builders especially for high-horsepower builds.

Here are the details:

  • Main bearings
  • .020" Undersized 
  • Made using softer metals 
  • Designed to allow a thin layer of oil lubricates the connection between the bearings and the crank allowing the crank to "float" to reduce wear
  • Note: Subaru main bearings are specific to either a #5 or #3 journal bearing position. Journal bearing position is not VIN or year specific, it must be known prior to purchase.​
