We have worked directly with Wiseco to offer the absolute best shelf stocking Pistons available for the Ford Modular Engines. These Pistons are an In-Board Forging, Strutted Skirt design capable of handling lots of Boost and / or Nitrous. Some of their features are a .300" Down Top Ring, Thick Skirts and Struts and Wiseco Armour-Glide Skirt Coating. The best thing about this Piston Set is the Rings. These Pistons are supplied with Wiseco GNX Piston Ring Set which uses a Gas Nitrided Steel Top Ring and Napier 2nd Ring with a 3 Piece Oil Ring. The Steel Top Ring is capable of withstanding large amounts of Boost and / or Nitrous, while the Napier 2nd Ring helps with Oil Control. We have been testing these Pistons / Rings for quite some time now and they are the absolute best we have seen.
52100 Tool Steel .200" Wall Wrist Pins are available as an upgrade - Suggested for 800+ HP
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 bench marking 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.
