With the emergence of PWC racing and the need for performance parts in the personal watercraft market, Wiseco has once again stepped up to the plate. We offer a wide variety of forged pistons and performance parts for nearly all of the popular PWC models. These high revving engines require the strength and durability that forged aerospace materials can provide. Wiseco offers many race proven parts for your Arctic Cat, Kawasaki, Polaris, Sea-Doo, Wet-Jet, or Yamaha.

Wiseco leads the performance aftermarket by producing the highest quality forged pistons for personal watercraft right here in the USA. Wiseco is unique because we forge all of our own pistons in house, and produce all of our own forge tooling right here in the USA. This allows us to control all aspects of our manufacturing process from raw bar to skirt coating finished parts. In addition, in-house dyno testing gives Wiseco the ability to develop state-of-the-art technology such as new shapes, coatings, and components, and lead the industry through rigorous R&D. Linking all segments of Wiseco’s organization through design, testing, manufacturing, and distribution allows us to fulfill market needs with minimum lead-times. 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.
