Fits: 2017 thru 2019 Chevy Silverado/GMC Sierra 2500HD/3500HD L5P Duramax Diesel

This Allison torque converter was designed with one purpose in mind, pulling. SunCoast initially developed this converter for the fleet customer who is on the road hot-shot driving or pulling heavy loads. The 1057 converter is 200-300 RPMs tighter than the factory converter. This converter will not spool an aftermarket turbo very well due to the efficiency of it. This converter would be perfect for a truck that tows and hauls constantly. In-town fuel economy could improve with this torque converter.

• Lower than factory stall speed, approx. 1800RPM
  
• Billet triple disc
  
• Perfect for constant & heavy towing applications
• Works best on stock turbo trucks
