Wiseco leads the performance aftermarket by producing the highest
quality forged pistons for domestic automobiles, sport compact and
racing applications 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.
Highly boosted, direct injection engines, such as GM’s LNF 2.0 require strict adherence
to the original dome and bowl design to maintain proper combustion characteristics.
Wiseco’s
new K635 series piston is the only forged piston utilizing special form
tooling for the correctly shaped dome and bowl design. Coupled with
Wiseco’s brush dome deburring, Nitrde steel XX rings, skirt coatings,
and extra stout 5mm wall
thickness pins (offset like the OE for noise reduction), this is the only forged piston with the technology needed to properly
compliment D.I.
