Product Details

ACL Race Series connecting rod bearings are engineered for high-performance and racing applications where extreme loads and temperatures demand superior bearing technology. These bearings feature ACL's advanced tri-metal construction with a steel backing, high-strength copper-lead intermediate layer, and a specialized overlay for exceptional durability and wear resistance.

Key Features:

  • Race Series design for maximum performance under extreme conditions
  • Tri-metal construction with steel backing for superior strength
  • -.025mm undersize for precision crankshaft fitment
  • Enhanced oil clearance characteristics for improved lubrication
  • High-fatigue strength copper-lead alloy layer
  • Proprietary overlay material for reduced friction and improved embeddability

ACL Race Series bearings are the choice of professional engine builders and racers worldwide. The -.025mm undersize allows for proper clearance when using a reground crankshaft or for achieving optimal bearing clearances in high-performance builds.
