Dodge NV4500 29 Spline 1-1/8th 10 Spline Input Shaft Full Bellhousing Kit for Jeep 4.0L 6 CYL (89-02 AX15 & NV3550 Replacement)
The overall assembly length is 24.750". The 4.0L Jeep 6 cylinder engine can easily be adapter to the NV4500 using the adapter bellhousing. The internal release bearing on the AX15's will be eliminated, and the external slave cylinder on the later model AX15 and the NV3350s is replaced with a new style slave cylinder. The bellhousing requires the installation of a new GM input shaft. NOTE: The installation of the new GM input shaft may require the transmission endplay to be reset.
When coupled to the AX15, the stock transfer case used a 23 spline input gear. This kit comes with a new 29 spline input gear for the New Process 231 transfer case.
The transfer case adapter is the shortest design possible to couple to the New Process transfer case shifter. Jeep TJs require a different transfer case shifter bracket which can be switch out before shipping the kit. See options below. These packaged kits include a new support crossmember which couples to the stock skid pan. Modifications will be required to your flooboard for the shifters, and the skid pan will require new holes to be drilled for the crossmember support. A body lift is normally recommended for clearance. Due to the different transfer case shift controls found on Jeep Cherokees, this kit should not be used with these vehicles.
These kits are also supplied with a new external slave cylinder. When coupling this new slave cylinder to your stock master cylinder, you will be require to use one of the following clutch fittings. The correct fitting will depend on which configuration you have on your stock master cylinder fitting.
