Wiseco Ford DOHC V8 4.6L 3 Valve NA/Boost/Nitrous Top Ring Down .300in -13.0cc 3.552 Bore 8.8:1 CR

If you're building a serious Ford 4.6L 3-valve DOHC V8 for racing, whether it's naturally aspirated, boosted, or running nitrous, Wiseco's Professional Series forged pistons are a solid choice. These pistons are designed from the ground up for heavy-duty performance applications where reliability under extreme stress is critical. They are forged and machined right here in the USA from 2618 aluminum, a material known for its improved tensile strength, making them well-suited for the demands of racing.

Wiseco has packed these pistons with features to ensure they perform and last. You'll find precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal, which is crucial for both power and engine longevity. The piston crowns are fully machined, and they include forced pin oiling to keep the wrist pins properly lubricated. Additionally, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. This comprehensive approach means these pistons are built to withstand severe duty and help you push your engine's limits.

This set includes eight pistons, each with a 3.552-inch bore and a -13.0cc dish volume, resulting in a compression ratio of 8.8:1. The top ring is positioned down .300 inches. Please note that 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.
