Wiseco Ford DOHC V8 4.6L 4 Val NA/Boost/Nitrous Top Ring Down .300in -16.0cc 3.552 Bore 8.5:1 CR

If you're building a serious Ford 4.6L DOHC V8 engine, whether for naturally aspirated performance, forced induction, or nitrous, Wiseco's Professional Series forged pistons are built to handle the extreme demands. These aren't your average pistons; they're crafted from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for heavy to severe duty race applications where reliability under stress is paramount.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. This attention to detail helps ensure consistent performance and durability. They also feature an ArmorGlide skirt coating, which helps reduce friction and noise while resisting seizure, and the crown is fully machined for a clean, precise combustion chamber shape. Plus, forced pin oiling is incorporated to keep the wrist pins properly lubricated under high loads.

This set is specifically for a 3.552 inch bore with a -16.0cc dish, resulting in a compression ratio of 8.5:1, making it a solid choice for boosted or nitrous applications where controlled compression is key. Keep in mind these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
