Description

Wiseco Professional Series pistons are designed to take the hard-driving abuse from your performance engine. They're forged from either 2168 or 4032 aluminum alloy for maximum strength, and then precision CNC-machined to their intricate final configurations under close tolerances. Where applicable, designs incorporate strength provisions to deal with turbocharging, supercharging, and nitrous. Chromoly wrist pins and Spirolox retainers are included. Choose the model tailored for your engine application.
