The table below lists every trim of the 2018 Dodge Ram 2500 Reg Cab LB 4WD with the engine, drivetrain, axle ratio, horsepower, torque, GVWR, curb weight, and payload that go with that trim's headline tow rating.

How to interpret the headline tow figure
Ratings in this range are typically achievable with a weight-distributing hitch and the appropriate tow package. The conventional bumper-pull rating without weight distribution will be lower than the headline figure shown here — usually 5,000 to 8,000 lb. Confirm the hitch class on your vehicle's door-jamb sticker before towing at the upper end.
