Installation Considerations

• All advertised stall speeds are based on a specific vehicle's setup and actual stalls will vary depending on your application. Please contact us for customized information.
• We recommend upgrading to a "Street Bandit Series" torque converter if you have upgraded two or more components (e.g., Intake, Heads, Headers, Exhaust, Camshaft, or Gearing).
• For applications involving power adders such as Nitrous Oxide (NOS), Turbochargers, Superchargers, or a Transmission Brake, we recommend upgrading to an "Out Law Racing Series" torque converter.
