A simple question that the internet and Dr Google cannot seem to provide a clear answer to.
Does the 48-11 use a chain instead of a clutch pack like the 44-44?
Found this statement that makes it sound like both the 48-11 and 48-12 use a chain.
The heart of the Ram 1500’s four-wheel-drive system is one of two electronically controlled BorgWarner transfer cases. The BorgWarner 48-12 offers part-time 4WD operation with 2-Hi, 4-Hi, and 4-Lo settings, and the BorgWarner 48-11 offers on-demand 4WD operation with 4Auto, 2-Hi, 4-Hi, and 4-Lo settings. The 4Auto set-it-and-forget-it setting provides full-time 4WD, which functions automatically to provide maximum traction in all road conditions. New for 2019, both transfer cases have a larger-diameter mainshaft and the chain and sprocket have been relocated for improved bearing support and improved lubrication. Also, the 48-11’s 4Auto on-demand system is enhanced for quicker response and higher front output torque capacity. Each transfer case is engaged via easy-to-use push-button controls, and each has a low-range ratio of 2.64:1, which helps create increased low-speed torque capability off-road.
