Wiseco Ford DOHC V8 4.6L 4 Val 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 DOHC V8 engine, whether for racing, heavy towing, or high-boost applications, this Wiseco Professional Series piston set is built to handle the stress. These aren't your average pistons; they're forged from 2618 aluminum right here in the USA, giving them improved tensile strength needed for demanding performance builds. The 3.552-inch bore size and 8.8:1 compression ratio are specified for engines designed for forced induction or nitrous, offering a solid foundation for significant power gains.

Wiseco has packed these pistons with features that serious builders look for. You'll find precision-machined ring grooves, anti-detonation grooves, and other features designed to improve ring seal and prevent detonation. They also come with an ArmorGlide skirt coating, which helps reduce friction and noise while resisting seizure. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pins lubricated under extreme conditions. This set is designed for heavy to severe duty performance applications, meaning they're built to take a beating and keep performing.

This set includes eight pistons, enough for a complete V8 engine. 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.
