Wiseco Ford SOHC V8 4.6L 2 Val NA/Boost/Nitrous Top Ring Down .300in -13.0cc 3.572 Bore 9.8:1 CR

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in your Ford 4.6L SOHC V8 engine. This material choice offers improved tensile strength, making them well-suited for demanding applications like forced induction (boost) or nitrous oxide systems, as well as heavy-duty naturally aspirated builds. The pistons are precision machined in the USA, ensuring tight tolerances and reliable operation.

Wiseco has incorporated several features to enhance performance and durability. The ring grooves are precisely machined, and the design includes anti-detonation grooves and additional ring seal improvements to help maintain compression and prevent blow-by, especially under high cylinder pressures. A notable feature is the ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling further contribute to the longevity and performance of these pistons in severe duty race builds.

This set includes eight pistons, each with a 3.572-inch bore and a -13.0cc dish volume, resulting in a 9.8:1 compression ratio when paired with appropriate cylinder heads. The compression height is 1.220 inches, and they utilize a 0.866-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for builders who are serious about extracting maximum performance and reliability from their engine.
