Piston Kit

WOSSNER
Image: Product/Part name
  • Forged Piston: Made from aerospace-grade aluminum alloy using a closed-die forging process, which aligns the grain structure for high tensile strength and fatigue resistance
  • Piston Skirt Coating: Most kits feature a specialized dry-lute or molybdenum disulfide surface coating on the skirts to reduce friction, prevent scuffing, and ease the break-in process
  • Piston Rings: High-quality piston rings designed to match the specific thermal expansion and sealing requirements of the piston
  • Wirst Pin: Precision-machined steel pin
  • Circlips: Secure clips to keep the wristpin in place
