The German company Wossner is a specialist and innovator in the manufacture of high performance pistons. These products are used at the highest level and tested in the most extreme conditions (race engines on dirt or asphalt, in competition or leisure).

Each piston is forged from a high quality aluminum alloy, and has a skirt with a graphite-based anti-friction treatment. The piston design is developed for high performance and optimum reliability. The shape of the dome allows the use of camshaft profiles used in competition (high lift).

The design of the segments contributes to the reduction of friction and is adapted to each application:

Atmospheric engine, turbocharged…
