      GM Allison 1057 Torque Converter- Triple Disk 2001-2010

      Our 1057-3D converter established a benchmark for performance torque converters. Often referred to as theMcRat, it has set numerous records at the strip since it's inception in 2005. Our #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 our #56 converter. If you're running the larger turbos and the wild tunes and need to spool, see our #55, #58 or #59 series converters.
