  • Large chamfer to accomodate larger crankshaft fillets
  • 3/4 groove main bearings to optimize bearing load carrying capacity and oil flow to rod bearings
  • 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
