Features

  • High-strength overlay plate with reduced thickness enhances fatigue resistance.

  • Increased crush for better bearing retention, keeping everything in place during those high-stress moments.
  • Elimination of flash plating on the back of the bearings improves heat transfer and maximizes grip with the housing.
  • Increased eccentricity compensates for bore distortion at high RPM, aiding in hydrodynamic oil film formation.
  • 3/4 grooved main bearings optimize load-carrying surface area and oil flow to the conrod bearings.
  • Tight, consistent wall tolerances ensure you maintain precise clearances for optimal performance.
  • Enlarged ID chamfers on bearing edges accommodate large fillet radii on performance crankshafts.
