Wiseco 2-Stroke Piston

• Product Details

  Important note: This piston is for a stock or oversized bore. Please measure your cylinder to check clearance before ordering.

  Standard Pistons:

  Wiseco leads the performance aftermarket by producing the highest quality forged pistons in the U.S.A. Wiseco is unique because they forge all of their own pistons in-house, and produce all of their own forge tooling in the U.S.A. This allows Wiseco to control all aspects of their manufacturing process from raw bar to skirt coating on the finished parts.

  • Much stronger than stock. Forged using the highest quality materials available resulting in a piston that provides excellent performance and durability.
  • Tight tolerances for quiet running. Featuring a race-ready dome finish with smooth edges for improved combustion flow.
  • More hours with peak performance between piston changes. The rings, wrist pin, and circlips are manufactured by Wiseco under their strict quality standards to make sure every piston kit fits correctly, ensuring top performance and long-lasting durability are achieved.
  • The Wiseco Pro-Lite Piston includes: piston, ring(s), wrist pin, and circlips.
  • Note: Oversize piston requires cylinder sleeving and top end bearing not included in kit.

  Extreme racing conditions demand the strength and toughness that only forged pistons can offer. Compared to cast pistons, forgings are tougher and more durable, and will stand up to the abuse that high performance motorsport applications require. Most castings are brittle, have no grain structure and tend to fail catastrophically when the material yield strength is exceeded. Forgings have condensed grain that is aligned to the features of the part, which produces higher mechanical properties, and resistance to impact and fatigue. Each forging is designed to optimize the strength-to-weight ratio, and maximize performance.

  Note: Image is for reference ONLY, actual contents will vary based on fitment.

  ArmorGlide Pistons:

  Wisecos new ArmorGlide skirt coating is the result of testing, development, and benchmarking through Wisecos rigorous in-house dyno program. The outcome is the ultimate in skirt coating toughness, lubrication, and bond technology working together to minimize friction, maximize horsepower, and provide improved wear resistance.

  Not only is ArmorGlide a high-tech lubricant that reduces friction, but it also allows the piston to be fitted tighter within the bore than a non-coated piston. The benefit of reducing piston to wall clearance is better ring seal and reduced noise from piston rock.

  Why choose Wisecos ArmorGlide skirt coating?

  • Lower friction increases the pistons efficiency and contributes to increased horsepower.
  • ArmorGlide actually compensates for uneven thermal growth of a piston bore, creating the perfect piston skirt profile for maximum power and bore sealing.
  • Wisecos ArmorGlide remains bonded to the base material for the typical life of the piston.
  • ArmorGlide skirt coating is applied only where needed so there is no inconsistent thickness or overspray into functional areas of the piston.
  • Wisecos computer controlled application process allows for an extremely consistent, uniform coating that follows the piston skirt profile.
  • Process times are tightly controlled so there is no compromise to the piston base material, heat treatment, or geometry; these times also provide the highest quality coating thickness and bonding properties.
  • After 67 years manufacturing pistons, Wiseco continues to be the industry leader in forged piston technology. They are dedicated to bringing you the latest technology.

  Choose Wiseco Pistons with ArmorGlide for your next high-performance or racing application!
