Product Details

ACL performance race bearings for the Honda H22A4.  ACL race bearings are manufactured with a tri-layer metal with a hardened steel backing in order to withstand high RPM conditions, high stress loads, and high temperatures.  Each ACL race bearing design features the following:

  • Large chamfer to accomodate larger crankshaft fillets
  • 3/4 groove to provide optimum oil supply to rods and to maximize load carrying capacity
  • Incresed crush and tighter wall tolerance for better seating
  • Improved overlay and reduced thickness for increased fatigue strength
  • Hardened steel backing to maintain crush under high loads and temperatures
