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.
