The Sun Coast GM-1057-3D Triple Disc Torque Converter for your 2001-2010 GM 6.6L Duramax established a benchmark for performance torque converters. Often referred to as the Mc Rat, it has set numerous records at the strip since it's inception in 2005. The Sun Coast #57 series incorporates a modified OEM stator and is coupled with the "Velocity Series" impeller. It allows good turbo spool-up with stock size turbos running mild tunes and also offers more efficient fluid coupling than the #56 converter.
