The unique combination of design, metallurgy and engineering come together to deliver what drivers expect from high performance Trimetal engine bearings. Features include:


  • 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.
