The Eaton UltraShift PLUS and Cummins Westport ISX12 G are available for Peterbilt’s Models 579, 567, 384 and 365. The Eaton UltraShift PLUS is available in the 13-speed MHP and 10-speed LAS series and the 11.9-liter Cummins Westport ISX12 G is available up to 400 horsepower and 1,450 lb.-ft. of torque.
