Wiseco Ford SOHC V8 4.6L 2 Val Trick Flow Twisted Wedge NA/Boost/Nitrous -16.0cc 3.552 Bore 9.4:1 CR

If you're building a high-performance Ford 4.6L 2-valve SOHC V8, these Professional Series forged pistons from Wiseco are a solid choice for serious racers and builders. They are specifically designed for Trick Flow Twisted Wedge heads and are intended for naturally aspirated, boosted, or nitrous applications, aiming for a 9.4:1 compression ratio with a 3.552-inch bore. These pistons are engineered and machined in the USA from 2618 aluminum, which offers improved tensile strength for demanding conditions.

Wiseco has packed these pistons with features to ensure durability and performance. You'll find precision ring grooves, anti-detonation grooves, and additional features designed to improve ring seal. The crown is fully machined for accuracy, and they incorporate forced pin oiling to keep the wrist pins lubricated under extreme stress. The ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which is notable in a high-performance build. These are built to withstand heavy to severe duty race applications, removing limits for your engine build.

This set includes eight pistons, designed to fit Ford 4.6L and 5.4L Modular engines with a 3.552-inch bore. 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 details.
