Key Features

  • High-strength overlay plate with a reduced thickness enhances fatigue resistance, ensuring durability under extreme conditions.
  • Hardened steel backs on all rod bearings provide superior support for the bearing lining and enhance retention within the housing.
  • Increased crush improves bearing retention, crucial for high-stress applications.
  • Elimination of flash plating on the back of the bearings enhances heat transfer and maximizes grip with the housing.
  • Increased eccentricity compensates for bore distortion at high RPM, facilitating the formation of hydrodynamic oil films.
  • 3/4 grooved main bearings optimize the load-carrying surface area and oil flow to the conrod bearings.
  • Tight and consistent wall tolerances help maintain precise clearances, essential for peak performance.
  • Enlarged ID chamfers accommodate larger fillet radii on performance crankshafts, making installation a breeze.
