We stock a full line of original equipment parts for the New Venture NP241DLD Transfer Cases used in 1998 to 2002 Dodge Ram 2500 4x4 trucks. The NP241DLD and NP241DHD differ considerably from earlier NP241D transfer cases used from 1987 to 1993 and the second generation NV241D introduced for the 2002 Ram 1500.
Starting in 1994, the stock Ram 2500 transfer case was the NV241DLD (Dodge Light Duty). Optional on the 2500 and standard on the 3500 was the NV241DHD (Dodge Heavy Duty). There were numerous design changes in the NP241DLD/DHD during its production life; making part(s) selection a bit tricky without the round transfer case build tag affixed to the rear case half. Most, but not all 1999 to 2002 Ram 2500 4x4 trucks with the High-Output Cummins Diesel NV5600 6 speed transmission use the NV241DHD.
Despite the many assembly variations, there are a few common characteristics shared by both DLD and DHD 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. 1998-2002-1/2 models have a transfer case mounted vacuum switch, which controls the front axle disconnect system. Late 2002 Ram 2500 and Ram 3500 4x4 trucks did not have the CAD feature so transfer casesfor these late production trucks will have an indicator switch for the dash display instead of a vacuum switch.
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. Every NP241DLD transfer case will have two-piece tailshaft housing and have a 1-3/8" diameter 32 spline rear output shaft. The NP241DLD uses a 1-1/4" wide drive chain and does not have a provision to mount a Power Take Off (PTO). 1998 to 2002 models do not have any provisions for a speedometer. The speedometer signal for these years is generated by the ABS sensor on the rear axle.
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. You also have to watch for variations within model years as input shafts.
