FEATURES:

  • High strength overlay plate with reduced thickness for improved fatigue properties
  • Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing
  • Increased crush for improved bearing retention
  • Elimination of flash plating on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and its housing
  • Increased eccentricity to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films
  • 3/4 grooved Main Bearings to optimize bearing load carrying surface area and oil flow to the conrod bearings
  • Tight consistent wall tolerances to help you maintain consistent clearances
  • Enlarged ID chamfers on bearing edges where required to accommodate large fillet radius on performance crankshafts
