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. Gaskets and seals provided in our Top End Kits are OEM quality, ensuring your freshly rebuilt engine is properly sealed.
