Wiseco Ford 4.6L SOHC V8 2 Valve Trick Flow Twisted Wedge NA/Boost/Nitrous Professional Ser Pistons

If you're building a serious Ford 4.6L SOHC V8 2-valve engine, especially one intended for heavy-duty racing with naturally aspirated, boosted, or nitrous applications, these Professional Series forged pistons from Wiseco are a solid choice. They are designed and built in the USA using 2618 aluminum, which offers improved tensile strength compared to other aluminum alloys, making them well-suited for the high stresses of performance builds.

Wiseco has packed these pistons with features aimed at durability and performance. You'll find precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The crown is fully machined for accuracy, and they incorporate forced pin oiling to ensure the wrist pin stays well-lubricated under extreme conditions. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and contribute to quieter operation, which is notable for a racing piston.

This set includes eight pistons, each designed for a 3.572-inch bore and a 1.220-inch compression height, with a 0.866-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are intended for severe duty performance applications where reliability and strength are paramount.
