Manufactured in Germany with options in 4032-T6 and 2618 T6 alloy’s, Wossner offers a large variety of applications for both road and race. Pistons of 4032 construction enable tighter tolerances with regards to piston to bore clearance, thus having better ring seal.
Proprietary ring manufacturing and design allow longer lasting and more durable components which offers better mileage for a forged application.
Barrel faced, nitride coating or chrome top compression ring allows optimum and quick bed in and seal.
Turbo charged applications have a 1.5mm axial height top ring which helps play a vital role in reducing the thermal load on the piston crown. This also offers more rigidity and longevity in the piston ring pack.
