  • Hardened steel backs on all rod bearings provide superior support for the bearing lining, ensuring enhanced retention within the housing.
  • Increased crush design improves bearing retention, reducing the risk of displacement under extreme conditions.
  • Elimination of flash plating on the bearing backs enhances heat transfer, maximizing the grip between the bearings and their housing.
  • Designed with increased eccentricity to counteract bore distortion at elevated RPMs, facilitating the formation of hydrodynamic oil films.
  • Features 3/4 grooved main bearings to optimize load-carrying surface area and improve oil flow to connecting rod bearings.
