Wiseco Ford DOHC V8 4.6L 4 Val NA/Boost/Nitrous Top Ring Down .300in -6.0cc 3.552 Bore 9.6:1 CR

This is a set of eight Wiseco Professional Series forged pistons, designed for Ford 4.6L DOHC V8 engines. You get the pistons themselves, ready to be installed in your engine build. These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for demanding applications.

Wiseco has packed these pistons with features for serious racers and builders. They include precision ring grooves, anti-detonation grooves, and other features to improve ring seal. The piston crowns are fully machined, and they also feature forced pin oiling to keep things lubricated. The ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly. These are built to handle heavy to severe duty performance, whether you're running naturally aspirated, boosted, or nitrous setups.

This set is specifically for a 3.552 inch bore with a 9.6:1 compression ratio. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
