Circle Track Converters
TCI Circle Track Torque Converters are designed with a stock appearance to satisfy rulebook requirements, but with a distinct performance advantage over OE torque converters. Circle Track Torque Converters have a lower positive lock-up stall speed that eliminates up to ten percent of the slippage that is common in OE converters. These TCI Circle Track Torque Converters feature a heavy-duty stator, furnace-brazed fins, and precision-certified stall speed. Reduced rotational weight provides improvements in off-the-corner acceleration, increases starting speeds and lowers transmission operating temperatures.
