Product Details

ACL Race Series connecting rod bearings deliver high-performance engine protection for demanding motorsports applications. Engineered with advanced tri-metal construction, these bearings feature a steel backing, high-strength copper-lead intermediate layer, and a proprietary overlay designed to withstand extreme loads and temperatures.

Key Features:

  • Race Series construction optimized for high-RPM and high-load conditions
  • 0.25mm undersize specification for precision machined or worn crankshafts
  • Tri-metal design provides superior strength and fatigue resistance
  • Enhanced oil retention grooves for improved lubrication
  • Manufactured to strict OE tolerances with race-proven materials

ACL Race Series bearings are trusted by professional engine builders and racers worldwide for their durability and consistency under extreme competition conditions. The undersize configuration allows proper fitment on crankshafts that have been ground or exhibit wear beyond standard tolerances.

So far good

Easy to order from. Shipping time pretty good.
