Wiseco's new ArmorGlide skirt coating is the result of testing, development, and benchmarking through Wiseco in-house dyno prog.. The outcome – minimized friction, maximum 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. Better ring seal reduces noise from piston rock. ArmorGlide is being applied to selected pistons.
