Dodge Cummins

From 1989 onward, the Cummins B Series inline 6 turbo diesel has powered heavy duty Ram pickup trucks. Dodge was the leader in bringing a light-duty diesel engine to the domestic full-size truck market starting with the legendary 5.9L 12 valve. This engine gained a reputation for its reliability and ability to go hundreds of thousands of miles without major repair. Since then, Cummins and Dodge have produced increasingly powerful work trucks, with modern 6.7 Cummins engines producing 1000 ft-lbs. of torque.

While Cummins engines are bulletproof, the transmissions behind them? Not so much. The transmissions used in Dodge’s diesel applications are not designed to sustainably withstand the abuse of a work truck.

From the early 518 up through the 68rfe installed behind the 6.7 liter Cummins, we are your experts in building the custom transmission you need to have it last as long as the Cummins powering it.

We work on the following Cummins transmissions:

  • 518 1989-1993
  • 47re 1994-2002
  • 48re 2003-2007
  • 68rfe 2007-2013

Modifications include but are not limited to:

  • Billet Single & Triple Disc Torque Converters
  • Suncoast Billet 2nd Gear Bands & Band Struts
  • Modified Valve Bodies
  • Shift Kits
  • Alto Red Eagle Clutches
  • Kolene Steel Plates

​We build Dodge Cummins transmissions to withstand horsepower levels encroaching 600 horsepower. Our “stock” rebuilds are what other shops and companies call “performance” or “heavy duty”. The technicians at our Hayden, Idaho location have the experience and skill needed to maintain or repair your Cummins powered Ram truck.
