This kit is designed to fit the 29 spline Dodge Standard Duty NV4500 transmission.
This kit requires the use of a stock 1989-93 Jeep AX5 bellhousing with the internal slave cylinder.
The overall assembly length is 25.625”. This kit is designed around the 1989-93 Jeep with the internal release bearing. If your AX5 has the external slave cylinder, we can switch the bellhousing adapter plate kit to accommodate the 1994 & later slave cylinder configuration. Our adapter plate will permit the NV4500 to bolt directly to the original bellhousing. The original slave cylinder configuration on this conversion is retained and a special Centerforce clutch disc will be required (Part No. 383824). Driveline modifications will be required when retaining the original 4 cylinder engine. Due to the added length a fixed yoke kit (P/N 50-7906) is highly recommended.
When coupled to the Peugeot or AX5, the stock transfer case used a 21 spline input gear. A new input gear must be installed to match the output spline of your transmission. NOTE: These new gears will only fit the NP231 transfer case, and the transfer case must be disassembled for installation of this input gear.
The transfer case adapter is the shortest design possible to couple to the New Process transfer case. This adapter comes with a shifter bracket that allows the use of your stock transfer case shifter. These packaged kits include a new support crossmember which couples to the stock skid pan. Modifications will be required to your floorboard for the shifters and the skid pan will require new holes to be drilled for our crossmember support. A body lift is normally recommended for clearance.
