Wossner GMBH and Wossner USA are known worldwide for innovative design and quality manufacture of pistons and connecting rods (con rods). Wossner are the preferred piston for many racing applications with over 25 years in the high performance racing industry. Wossner pistons are forged not cast giving a stronger piston with less impurities in the end result. Moly coating on the skirts gives less heat transference.

In 2009 Wossner acquired an in house forging facility FGM (Forged Group Monale) improving control over quality of manufacture. Only 4032 and 2618 Aluminium alloys are used for their pistons and 4340 steel alloy for their con rods.

After extensive research and development products are tested in their FEA (Finite Element Analysis) computer simulation ensuring Wossner products are optimum for performance and quality.
