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.
