The second generation Dodge/Ram HD trucks debuted in 1994 and are a breakthrough after more than 20 years of what was essentially the same truck. Its power wagon-style styling and interior appointments were a step up from the Chevy Silverado and Ford F-Series icing on the cake. But, understand that second-generation Dodge/Ram HD trucks still use diesel engines.
Did Cummins Make Improvements to Dodge and Ram Engines?
So the second generation applied to Cummins engine is a misnomer. The 5.9-liter Cummins diesel actually appeared in the 1989 Dodge trucks and lasted until 2002. But during that time, the 5.9-liter diesel saw two different versions. Previous 1994 to 2002 Dodge/Ram versions feature mechanical injection but electronic fuel pumps using a Bosch P7100 pump.
It appeared in 1999.
How was the 5.9 Cummins improved in 1999?
The heads now featured four valves per cylinder. And although the injectors are still mechanical, it used an electronic injection pump controlled by the improved engine control unit. Airflow is greatly improved from the 12 valves. With an available five-speed manual transmission, Ram trucks increase performance to 215 horsepower and 420 lb-ft of torque.
By 2000, that performance had increased to 235 horsepower and 460 lb-ft of torque. Through 2002, these used a five-speed manual transmission. Not to be confused, but in the last two years of the second-generation Dodge/Ram, the company has added a high-output 5.9-liter with 245 horsepower and 505 lb-ft of torque. This is achieved through the higher compression and new NV5600 6-speed manual transmission.
What are you looking for
As for the trucks themselves, there were both club and crew cab versions. There was a short bed and a long bed. Dual rear wheels were available on the 3500 truck, as was all-wheel drive.
All in all, the second generation HDs’ engines combined with the 5.9-liter Cummins diesel engine make them highly collectible today. Prices are all over the place depending on the condition, mileage and options the truck came with. Any modifications are also factored into the price.
Mods can include larger injectors and twin turbocharging, along with more expensive processes like larger bores and longer stroke bars. Things to consider with the newer 5.9 engines is the Bosch electric fuel pump. Accordingly, an aftermarket version is your best bet or a recent replacement with a new OE pump is in order.
