Product Details

  • 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
