This new input gear is a 29 spline female and has been modified to fit a Jeep NP241 with the 2.72:1 low gear ratio. The transfer case needs to be dis-assembled to install the new input. This input can be used when adapting to a GM 29 spline transmission like the 6L90. Adapter 50-9600 would need to be ordered with the 52-9945.
The shaft could also be used for the Dodge transmission, like the NV4500 4WD.
