Each forging is designed to optimize the strength-to-weight ratio, and maximize performance. Extreme racing conditions demand the strength and toughness that only forged pistons can offer.
Most castings are brittle, have no grain structure and tend to fail catastrophically when the material yield strength is exceeded. Picture may not match actual product manufacturers Wiseco leads the performance aftermarket by producing highest quality forged pistons for domestic automobiles, sport compact and racing applications right here in USA. Forgings have condensed grain that is aligned to the features of part, which produces higher mechanical properties, and resistance impact fatigue.
Compared to cast pistons, forgings are tougher and more durable, will stand up the abuse that high performance motor sport applications require.
