This Wiseco Piston / Rod Combo features 5.4L Specific Pistons with a 1.330" Compression Height which brings the piston up to the top of the deck. The standard 4.6L / 5.4L Pistons will sit .120" down in the cylinder on the 5.4L block which takes away quench and combustion efficiency. By raising the compression height we are able to improve combustion and flame travel which results on a more complete burn and more power. This is a great choice for all 5.4L's. The Pistons also feature super thick Skirts and Struts and a .300" Down Top Ring for added strength, as well as Wiseco's Armour Glide Skirt Coating. The K1 H-Beam Rods feature 7/16" ARP 2000 Rod Bolts and are some of the strongest H-Beam Rods available for the 5.4L Engines. This Kit also comes with Piston Rings. Wiseco GNX Ring Set uses a Steel Nitrided Top Ring and a Napier 2nd Ring and is able to handle boost pressures of over 50 PSI.
