Performance Automatic Torque Converter, 12 Inch 2004R Lock Up, 2200 RPM Stall PA20201

Performance torque converters are generally grouped by size (diameter) and stall speed.As the diameter of a torque converter decreases, the stall speed (RPM) goes up. Most of the factory spec torque converters are 12-13 inch diameter and have a stall speed around 1600-1800 RPM. This promotes excellent fuel economy and driveability because they are specifically designed for these purposes.The problem arises when the modifications are done to the fuel system, camshaft or other engine control systems. Smaller diameter torque converters are needed to provide more slip at idle. This allows engines with a lot of camshaft to idle better. As the torque converter and horsepower range is moved higher through the RPM range, the smaller torque converters with their higher stall speeds provide maximum torque multiplication where needed. Also, the same torque converter will react differently when used behind different engines. Performance Automatic converters will make your car or truck perform to its utmost potential.12 Inch Converters:Performance Automatic has combined a true performance feel and value price to its 12 inch torque converters.
