The 44-84 transfer case from BorgWarner is a new generation AWD/Part time 2-speed transfer case with a 2.64 low range. This transfer case was developed for the General Motors H2 and contains almost 31 pounds of powder metal components. The powder metal components range from single level gears, to two planetary carriers one of which is a two piece sinter brazed assembly and the other a highly designed 3 piece center differential which in open mode distributes torque in a 40/60-ratio front to rear. The center differential carrier body contains three sections and two different materials. In addition to the carrier body, the differential contains 8 pinion gears, which are P/M, and two sun gears, one of which is P/M.
