True 50:50 four-wheel drive. The stock Mercedes Sprinter transfer case splits the power delivery at 70:30 with only 30% of the total power available to the front axle. With the Atlas installed not only do you have the full 50% available to both axles, you also have the option to select each axle independently in the event that you want to only drive the front or rear (front or rear “dig”) for specific off road maneuvers, something previously impossible with the stock configuration of the Mercedes Sprinter chassis.
