Description

The Sun Coast GM-1057-3D Triple Disc Torque Converter, also known as the "McRat," is designed for heavy-duty applications like hot-shot driving or pulling heavy loads. It features a modified OEM stator and a "Velocity Series" impeller for efficient fluid coupling. This converter is ideal for towing and hauling, and it may improve in-town fuel economy. It will not spool an aftermarket turbo very well due to its efficiency.
