Wiseco Ford DOHC V8 4.6L 3 Valve NA/Boost/Nitrous Top Ring Down .300in -20.0cc 3.552 Bore 8.2:1 CR

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance builds, especially those pushing the limits with forced induction or nitrous. The material choice here means improved tensile strength, which is crucial when you're dealing with the extra cylinder pressures that come with boosting or spraying. They're designed with a -20.0cc dish, resulting in an 8.2:1 compression ratio when installed in a 4.6L 3-valve Ford DOHC V8 with a 3.552-inch bore. This lower compression is ideal for managing boost or nitrous safely.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves and anti-detonation features to ensure better ring seal and prevent detonation. They also feature an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and keep things quieter during operation. The forced pin oiling design ensures the wrist pin stays well-lubricated, a critical factor in high-stress applications. The fully machined crown also contributes to the overall durability and performance of the piston.

This set includes eight pistons, designed to withstand heavy to severe duty performance applications. Keep in mind these are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and durability in their Ford modular engine, these Wiseco pistons are a solid choice.
