Wiseco Ford DOHC V8 4.6L 4 Val NA/Boost/Nitrous Top Ring Down .300in -20.0cc 3.552 Bore 8.2:1 CR

If you're building a serious Ford 4.6L DOHC V8 engine, whether for naturally aspirated, boosted, or nitrous applications, this Wiseco Professional Series piston set is designed to handle the extreme demands of racing. These pistons are forged and machined right here in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high stress conditions.

Wiseco has packed these pistons with features for durability and performance. You'll find precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal, which is critical for maintaining compression and preventing blow-by. The fully machined crown ensures accuracy, and the forced pin oiling helps keep the wrist pins properly lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, making them suitable for heavy to severe duty race builds where reliability is paramount.

This set includes eight pistons, each with a 3.552-inch bore and a -20.0cc dish volume, resulting in a compression ratio of 8.2:1. Please note that these pistons are not CARB approved and cannot be shipped to California.
