This Wossner piston kit features a forged high-performance piston with skirt coating and a standard bore size of 43.50mm. It is designed for efficient heat transfer from the combustion chamber to cylinder walls and has an elliptical design for a uniform bearing surface under thermal expansion. This ensures even distribution of thrust loads and prevents piston collapse under high-stress conditions. The piston size is 43.45mm. Manufactured in Germany, this piston kit is built to withstand rigorous use. Cross-reference OEM part numbers include Wossner 8306DA, 56-W9991.A.WO, and BR8-11631-01-A0.
