Wiseco Ford DOHC V8 4.6L 3 Valve NA/Boost/Nitrous Top Ring Down .300in -16.0cc 3.552 Bore 8.5:1 CR

Forged from 2618 aluminum right here in the USA, these Wiseco Professional Series pistons are built for serious Ford 4.6L 3-valve V8 engines, whether you're running naturally aspirated, boosted, or nitrous setups. The 2618 aluminum alloy offers improved tensile strength, which is crucial for handling the extreme pressures found in performance builds. This set is specifically designed for a 3.552 inch bore and features a -16.0cc dish volume, resulting in a compression ratio of 8.5:1, making it a solid choice for forced induction or high-performance naturally aspirated applications.

Wiseco didn't cut any corners with these pistons. You'll find precision-machined ring grooves, anti-detonation grooves, and additional features designed to improve ring seal, all contributing to better combustion efficiency and durability. The piston crowns are fully machined for accuracy, and they include forced pin oiling to ensure the wrist pins stay well-lubricated under high stress. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit for both street and track use.

This set includes eight pistons, designed to withstand heavy to severe duty performance applications. While these pistons are built for extreme use, please note they are not CARB approved and cannot be shipped to California. If you're building a high-performance Ford modular engine, these Wiseco pistons are a well-built option ready for your project.
