Wiseco professional series pistons have been designed to take the abuse from your high performance engine. For maximum strength, they're forged from either 2168 or 4032 aluminum alloy, 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.
