Dodge RAM Gen 5 5.7 Hemi 4WD Transfer Case

inventory at Buy Mustang parts Ltd, the Gen 5 (DT) Ram 1500 transfer cases represent a major shift in technology from the older BW 44-series. In 2019, Ram introduced the BorgWarner 48-series, which uses electromechanical on-demand (EMOD) technology for faster engagement and higher torque handling.

There are two primary versions for the 5.7L HEMI. To maintain your “luxury parts” standard, it is critical to distinguish between them based on the truck’s trim and 4WD selector buttons.

1. The Two Primary Transfer Case Options

• BW 48-11 (Active): This is the high-value “Luxury” unit. It uses an internal clutch pack to automatically shift power to the front wheels when it detects slip. It is the only one that allows driving in 4WD on dry pavement safely.

• BW 48-12 (Standard): This is a traditional mechanical locker. It is preferred by off-road purists (like Rebel owners) because it provides a 100% solid lock between front and rear axles, but it should never be used on dry pavement.
