Wiseco pulled out all of the stops with their Professional Series piston kits. These pistons 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. Successfully tested in the highest horsepower applications, the Professional Series kits also utilize ArmorGlide skirt coating—which 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. Anti-detonation and pressure seal grooves give you a better ring seal, reducing noise from the piston rock and delivering better performance. Order the pistons tailored for your application.
