Summit Racing™ Pro LS Torque Converters Can Handle Up to 600 Horsepower

f you’ve modified your GM LS engine to make more steam, you should definitely consider upgrading your automatic transmission with a Summit Racing™ Pro LS Torque Converter. Rated to handle up to 600 rear wheel horsepower, the Pro LS converters provide the extra stall speed you need for quicker acceleration and faster launches.

The Pro LS torque converters are built solid, too:
• Fully TIG welded and furnace brazed
• Computer balanced
• New pilot bushing, impeller hub, and turbine hub
• Custom stator
• Woven carbon fiber lockup clutch lining
• Heavy-duty Torrington bearings
• Most converters have anti-ballooning plates to handle turbo and nitrous applications

A gentle reminder—the stall speed ratings listed are for reference only. A torque converter’s actual stall speed is dependent on your engine combination, gearing, and vehicle weight.
