_______________________________________________________________________________  Instead of the age-old system of the gearbox splining onto the existing transfer case splines, the latest version of the blackbox - dubbed the blackbox-i for integrated - replaces the input shaft and bearing retainer. This means the transfercase's input gear slides directly onto the BlackBox output shaft and thus creating a 'single' transfer case unit. 
This is top reason we have created this underdrive unit.When integrated into the Atlas II or Stack line-up, this 2.72:1 unit only adds 4"! For transfer cases that do not have large input retainer or clocking ring - it only adds 5".It gets better. In some cases it is shorter than stock; A blackbox-i coupled to a Dana300 is shorter than stock wranger NP231! 
Complete RollerBearing Support: The BlackBox-i is the only Planetary Gear Box that has a bearing support at both the input and output of the mainshaft. Our competitors rely on the input splines and bearing of your transfer case to both center and support all the output load of the gearbox. Not here. Self-sufficient Unit: The BlackBox-i is a closed system and does NOT rely on fluids from your transfer case. It has its own drain plug , fill plug, and breather. 4140 Chromoly Mainshaft: The BlackBox-i uses a 4140 Mainshaft that has been through-hardened for the ultimate in shaft strength. Looking for a weak link? Look elsewhere. Hard Anodized Black: All of our Black Box Gear Boxes are hard anodized black, giving a lasting constistant surface finish. This small detail can make all the difference in coastal climates and in trucks that are exposed to de-icing salt and chemicals. The BlackBox-i is compatable with the following transfer cases that have a input gear seperate from the input shaft. - Bronco Dana 20 - Jeep Dana 300 - Atlas II - StaK line The input of the blackbox is most directly compatible with domestic transmissions and transfer cases that share the common '6 bolt round' transfer case pattern. These applications will allow integration of the Black Box with few or no adaptors required. The blackbox-i is currently avaialable with input spline counts of 21, 23, 27, 29, 31, and 32.
