Wiseco Pistons

Automotive Forged Piston Advantage

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. 
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.


Our forged pistons offer our new ArmorGlide™ skirt coating, which is the result of testing, development, and benchmarking through Wiseco’s 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 allowing a better ring seal and reduced noise from piston rock.
