More details

More info

  • Wossner forged pistons are superior in strength and design.
  • 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.
  • Made in Germany
