  • Engineered to provide the best possible path for combustion chamber heat transfer to cylinder walls.
  • Elliptically designed to provide a more uniform bearing surface under piston heat expansion, eliminating localized pressure and distributing thrust loads more evenly, thereby preventing piston collapse.
