1994-1997 Dodge NP241DHD Introduction
The New Process NP241DHD (Dodge Heavy Duty) Transfer Case was Optional on 1997 Ram 2500 and standard on the Ram 3500. There were numerous design changes in the NP241DHD during its production life; making part(s) selection a bit tricky without the round transfer case build tag affixed to the rear case half.
Despite the many assembly variations, there are a few common characteristics shared by all 1994-1997 NP241DHD models. All these cases will have a slip yoke rear output, left drive chain front output, with CV flange and mechanical shift engagement. The cases will also have a 6-gear planetary 2.72:1 ratio low range. All 1994-1997 NP241DHD units have a transfer case mounted vacuum switch, which controls the front axle disconnect system. Also, mechanical speedometer output was used for all years.
All 1998 and 1999 plus some 2000 gas V8 trucks with a manual transmissions and all automatic trucks regardless of their engine have a 23 spline input. Whereas, all manual transmission trucks with a Cummins Diesel or Gas V10 engine will have a 29 spline input shaft.
The NP241DHD has a 1-1/2" wide chain, a bearing supported planetary, and a SAE 6 Bolt PTO opening on the right side. 1994-1996.5 Transfer Cases had a 1-3/8" x 32 Spline Rear Output Shaft and a two piece rear output housing. 1996.5-1997 NP241DHD Transfer Cases have a 1-5/8" diameter 31 spline output shaft and a one-piece tail housing and take a slip yoke that is about 2-3/16" in diameter. If you are trying to swap parts between cases you will find some parts are interchangeable between the DLD and DHD models for a given year, but many are not.
