Wiseco has built pistons for most major forms of motorsports, from off-road to rally, Formula 1 to drag racing. So, their pistons benefit from some heavy-duty engineering experience. 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.
Warranty
Due to the multiple variables possible with any engine combination, all compression ratios listed are approximate. To accurately calculate the static compression ratio of any engine, the following values must be known: Bore diameter, stroke length, rod length, deck height, combustion chamber volume, cylinder head gasket compressed thickness, and cylinder head gasket bore diameter.
