Performance Automatic 574611 Ford C4 Torque Converter, 2500-2800 Stall

Performance torque converters are generally grouped by size (diameter) and stall speed (RPM). As the diameter of a torque converter decreases, the stall speed goes up. Most factory torque converters are 12-13 inches in diameter and have a stall speed around 1600-1800 RPM. Problems arise when modifications are done to the fuel system, camshaft, or other engine control systems. Smaller diameter 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 in the RPM range, small torque converters with their higher stall speeds provide maximum torque multiplication where it's needed. Also the same torque converter will react differently when used behind different engines. So make your torque converter selection with the help of qualified personnel. Performance Automatic has endless converter combinations to make your car or truck perform to its utmost potential.
