Wiseco leads the performance aftermarket by producing the highest quality forged pistons for domestic automobiles. Wiseco is unique because they forge all of their own pistons in house. This allows them to control all aspects of our manufacturing process from raw bar to skirt coating finished parts.  New ArmorGlide™ skirt coating 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.  ArmorGlide™ reduces friction and allows the piston to be fitted tighter within the bore allowing a better ring seal and reduced noise from piston rock.
