The Dana 300 is largely considered one of the best transfer cases offered by Jeep. It comes of no surprise that people will want to use it outside of its original application. #52-0208 is a 32 spline input shaft to replace the original 23 spline input shaft on the Jeep Dana 300. Customers who typically purchase this input shaft are planning on utilizing the Dana 300 up against certain Chevy transmissions with 32 spline output shafts. It should be noted this input shaft is normally sold in kits #PN50-6404 and #PN50-0401 to mate TH400 and 4l80E transmissions to the Jeep Dana 300. These kits also include an adapter as is required for most applications. In the past, we have received a few requests for purchasing this input shaft separately.
