There are absolutely no compromises with ATI sprag-equipped Treemaster® racing torque converters! Unlike other torque converter manufacturers that use refurbished OEM parts, ATI uses all new components. In fact, ATI is the only independent company that has this capability. Because of its ability to control all aspects of the manufacturing process, ATI has the advantage of designing each component for optimum efficiency and total durability.

Each Treemaster® racing torque converter is custom configured to your exact application to put the power to the ground. It’s the perfect compliment to an ATI racing transmission.

Treemaster Torque Converters include such features as the “C” series roller clutch, anti-ballooning plates, centerless ground hub, inner blade support, Torrington bearings and furnace brazing. They’re race-quality units designed for optimum performance and reliability, run after run!
