Wiseco leads the performance aftermarket by producing the highest quality forged pistons for Harley-Davidson in the USA.

• Wiseco is unique because they forge all of the pistons in house and produce all of their own forge tooling in the USA.
• This allows them 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 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 of your Harley-Davidson Motorcycle.
