Wiseco pulled out all of the stops when designing these professional series piston kits. These pistons are designed to accommodate the reluctor ring on stroker cranks without having to notch the pin bosses. Offset pins like OE and skirt shapes are specifically designed for street applications, making these the best piston kits available. They have been successfully tested in the highest horsepower applications. Wiseco's professional series piston kits also utilize ArmorGlide skirt coating. ArmorGlide is the result of testing, development, and benchmarking through Wiseco's in-house dyno program. The outcome is minimized friction, maximized horsepower, and 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 than a non-coated piston. A better ring seal reduces noise from the piston rock and offers better performance.
