Important Considerations

• Stall range performance is highly dependent on the specific vehicle setup. Please contact us for individualized technical consultation.
• Most vehicles, especially those with taller tires or increased gearing, may require additional gear reduction to achieve ideal performance.
• If you have upgraded intake, headers, exhaust, cam, or gearing, we recommend upgrading to our "Street Bandit Series" converter.
• For builds featuring power adders (Nitrous, Turbocharger(s), Supercharger, or Trans Brake), the "Out Law Series" is recommended for ultimate durability.
