About Wossner Piston Kits

• All Wossner pistons are forged in-house from aluminum
• Forging gives the alloy a better grain flow, which in turns creates more tensile strength, or the ability to bend without breaking.
• All pistons are machined on state-of-the-art CNC machine equipment, then hand finished and inspected for quality.
• The forged pistons come complete with gudgeon pin, clips, and high-performance rings.
