[edit] Transmissions
Transmissions for the Ram were the lower geared
A500/42RH-RE for light duty applications found behind the 3.9 L V6, the
A518/46RH-RE for more heavy duty applications found behind the 5.2 L and 5.9 L V8 engines, and the
A618/47RH-RE for heavy duty use behind the V10 gasoline and Cummins diesel engines. The 47RH was used in 1994 and 1995 model years, while the 47RE was used from 1996 through 2002. A
NV3500 was offered in 1500 Rams and light duty 2500 Rams. A
NV4500 was standard in 2500 and 3500 trucks (
except the uncommon, light duty 2500 rams). A NV5600 was offered in 1999 and 2000 Rams and was the only transmission offered behind the High Output diesel in 2001 and 2002.
[edit] Transfer cases
There were a total of 5
transfer cases for the four wheel drive Ram. All were part time and had a low range of 2.72:1. The 1500 featured a NP231 and NP231HD. The NP241 was standard on V8 2500 Rams. The 2500 and 3500 V10 and Diesel featured a NP241DLD from 1994-1997. In 1997 the NP241DHD became a option for 2500 Rams and was standard on 3500 Rams from 1998-2002.
[edit] Axles
The Dodge Ram featured a wide variety of axles. For the front axle of 4x4 Rams, a
Dana 44 was used on all 1500 Rams and
some, early, light duty 2500 Rams. However, most of the 2500 and all 3500 Rams used
Dana 60 front axles. The
1500 Rams and some early light duty 2500 Rams used a 9.25 Chrysler axle in the rear. A
Dana 60 rear axle was used on heavy duty 2500 V8 Rams. A
Dana 70 rear axle was used in 2500 Rams with a V10 or a Diesel/Automatic transmission combination. A
Dana 80 rear axle was used on 2500 Rams with a manual transmission and diesel engine combination and all 3500 Rams. The front solid axles in these rams were unique in the fact they didn't feature
Locking hubs, but featured a
Center axle disconnect. The 2002 2500 and 3500 Rams saw the eventual phase out of the Center axle disconnect, in favor of front axles that were permanently locked in. Dodge continues to feature front axles like this for their 2500, 3500, 4500, and 5500 trucks.
[edit] Engines
A
natural gas engine debuted for 1995 but was not popular and was only used in fleet vehicles on a very limited production run. The
Cummins B Series engine was switched from the 12-Valve to the 24-Valve (ISB) in the middle of the 1998 model year Dodge Rams due to emissions regulations. The ISB featured a new computer controlled injection pump, 24 valve head design and a electric fuel transfer pump.
