FAQs about the 1998.5-2002 Ram 2500 & 3500 Cummins Diesel engines and trucks

What are the stock horsepower and torque ratings for the 1998.5-2002 Ram 2500/3500 Cummins?

The 5.9L Cummins Turbo Diesel in the 1998.5-2002 models produces 235-245 horsepower and 460-505 lb-ft of torque, depending on the specific model year and configuration.

What is the largest wheel and tire combo that can be run at stock height for the 1998.5-2002 Ram 2500/3500?

At stock height, the largest tire size that generally fits is 33 inches on 16- or 17-inch wheels. Fitting 35-inch tires will typically require a leveling kit or trimming, especially on 4WD models.

How reliable are the engine and transmission on the 1998.5-2002 Ram 2500/3500 models?

The 5.9L Cummins 24-valve engine in this generation is highly reliable, often considered one of the most durable diesel engines produced. The 47RE automatic transmission, however, is less robust under heavy towing. The NV5600 6-speed manual is preferred for towing durability.

What are the fuel economy estimates for the 1998.5-2002 Ram 2500/3500 Cummins?

Drivers typically report 14-20 MPG from the 5.9L Cummins, with highway driving yielding the best results. Towing or heavy loads will reduce MPG to the lower end of the range.

What are the towing capacities for the 1998.5-2002 Ram 2500/3500 Cummins?

The Ram 3500 can tow up to 13,900 pounds, depending on the configuration, while the Ram 2500 maxes out around 12,000 pounds when properly equipped.

How easy is it to get more power out of the 5.9L Cummins engine?

The 5.9L Cummins 24-valve is highly responsive to performance upgrades. Gains of 100+ horsepower can be achieved with diesel tuners, cold air intakes, and exhaust systems. More aggressive power increases can be achieved with turbo upgrades and injectors.

What lift kit options are available for the 1998.5-2002 Ram 2500/3500?

There are many lift kits available, ranging from 2.5-inch leveling kits to 6-inch suspension lifts. Brands like Carli, BDS, and Rough Country offer solutions for better off-road performance and enhanced ground clearance. Now that these trucks have some age on them, we strongly recommend all rubber bushings, mounts, and steering components be checked and replaced before adding a lift, to ensure the best ride quality and safety.

Are there any known weaknesses in the engine or transmission of the 1998.5-2002 Ram 2500/3500?

The 5.9L Cummins engine is highly reliable, but some early long blocks still suffer from the so-called Killer Dowel Pin (KDP) issue. The 47RE automatic transmission is known to struggle with durability under heavy towing conditions and even stock torque figures. The VP44 fuel injection pump has some known weak points and can fail if the fuel system is not properly maintained.

How capable is the 1998.5-2002 Ram 2500/3500 for off-road use?

With lift kits, off-road tires, and locking differentials, these trucks are very capable off-road. While the stock suspension is decent for light off-roading, aftermarket upgrades are common for more rugged terrain.

What is the payload capacity for the 1998.5-2002 Ram 2500/3500?

The Ram 3500 has a maximum payload capacity of 3,910 pounds, while the Ram 2500 can carry up to 2,750 pounds, depending on the configuration and equipment.
