Wiseco Ford DOHC V8 4.6L 4 Val NA/Boost/Nitrous Top Ring Down .300in -16.0cc 3.572 Bore 8.5:1 CR

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston set is built for Ford DOHC V8 engines with a 4.6L displacement, designed to handle serious power from naturally aspirated, boosted, or nitrous setups. These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for heavy to severe duty race builds where reliability under extreme stress is critical.

Each piston features precision ring grooves, an anti-detonation groove, and additional features designed to improve ring seal, which is crucial for maintaining compression and preventing blow-by, especially when pushing the limits of your engine. The crown is fully machined for accuracy, and they come with forced pin oiling to ensure the wrist pins stay well-lubricated. The ArmorGlide skirt coating is applied to reduce friction and resist seizure, contributing to quieter operation and longer life even in demanding conditions. This set is designed to achieve an 8.5:1 compression ratio with a -16.0cc dish volume and a 3.572-inch bore size.

This set includes 8 pistons. 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.
