Valve Body with Maximal Torque Converter Stall

Speedmaster Full-Manual Valve Bodies deliver clean, crisp, and quick shifts by incorporating an adjustable pressure regulator that transmits power to the rear tires. These units are precision-machined from billet aluminum for weight savings and added strength. Some units are available with an integral trans-brake that enables the engine to turn rpm equal to the torque converter stall, thus propelling your race car to the finish line.
