2003-2004 Ram 5.9L Cummins Engine Upgrades

While the 5.9L Ram Cummins had pretty impressive power when they first rolled off the assembly line, they've been largely overshadowed by newer Ram trucks. The good news is that the 5.9L Cummins is just itching to make more horsepower with even the most basic of modifications and parts. That's why our selection of Ram 5.9L 2500/ 3500 Cummins Engine Upgrades is the first stop for most owners of 2003-2004 Ram 2500 & 3500 diesels. These Ram engine upgrades can give your truck a huge bump in horsepower, torque, and throttle response all in one place. One of the most effective ways to give your Ram 5.9L Cummins an utterly massive increase in power and torque is with a Ram 5.9L Cummins Tuner and Monitor. These Ram tuners come with new software for your Ram's ECM that change up key parameters of your Ram's engine management system so that you get a bunch of power without the need for any "hard" performance parts at all. These new Ram performance tunes increase boost pressure, adjust fueling, and change other functions so that your Ram 5.9L makes big-time horsepower and torque gains. One of our favorite tuners is the Ram Cummins Edge CTS3. The Edge CTS3 comes with extremely powerful performance tunes that will have your Ram 5.9L Cummins ripping around the street, sled pull, or trail in no time. The Edge CTS3 comes standard with a huge color touchscreen display that makes it one of the most effective engine monitoring systems on the market for the Ram 5.9L Cummins.

Even though aftermarket tuning can get your Ram Cummins huge power, tuners are on the pricey side and all that power may not be a great idea for Ram 5.9L trucks with a lot of miles on them. If you're looking for something more budget-friendly and mild-mannered in the power department, take a look at our Ram 5.9L Cummins Cold Air Intake Kits. These intakes provide your Ram's motor with a larger volume of charge air at cooler temperatures and higher velocities than stock which gives your 5.9L Cummins a nice increase in horsepower and torque. Ram cold air intakes are extremely easy to install, making them a hassle-free upgrade for your tough 5.9L Cummins Ram build. One of our most popular Ram Cummins intake kits is the S&B Oiled Cold Air Intake. S&B's intake features a highly efficient design and high-quality construction in budget-friendly package, which makes it perfect for nearly any 5.9L Cummins Ram. S&B's intake comes with a high-flow filter, a complete air box assembly, and full inlet tubing that completely replaces your OEM intake system and gives you excellent performance gains.

2003-2004 Ram 5.9L Cummins Leveling Kits

The Ram 2500s and Ram 3500s may have some good power, but one of their big downsides is their stock suspension setup that gives them a ton of front rake that's fine for towing, but just looks odd on a normal truck and really limits you when it comes to wheel and tire sizes. The good news is that we have plenty of Ram 5.9L Cummins Leveling Kits that can help you out with both issues. These leveling kits add just enough front ride height to your Ram so that it gets a clean, even front-to-rear stance and the ability to mount up bigger wheel and tire combinations. We carry leveling kits that range from budget-friendly and fairly basic leveling spacers to powerful and complete suspension system overhauls that will give your 5.9L Cummins Ram better on-road handling and awesome levels of off-road performance. One of our most popular Ram 5.9L Cummins leveling kits is the Carli 3" Starter System Leveling Kit. Carli's Starter System comes with a pair of leveling springs that add all the ride height your Ram needs to get a great look, but also includes a full set of Carli Signature Series Shocks that give your Ram excellent on-road handling and better off-road performance than the stock shocks.

2003-2004 Ram 5.9L Cummins Lift Kits

While a leveling kit will clean up your Ram's rake and let it fit decent tires, if you're looking to add some seriously huge tires to your Ram build, you're going to need more ride height than what a leveling kit can give you. For fitting really big tires, your best bet is our selection of Ram 5.9L Cummins Lift Kits. These lift kits give your Ram a big bump in both front and rear ride height so that you get the clearance to mount up huge wheel and tire combinations. We have lift kits in a variety of different lift heights and sizes so that you can give your Ram 5.9L Cummins build the look you want and the clearance you need for your choice of tires. We have lift kits that can fit any budget or application, from basic, budget-friendly systems that only come with the core lift components to extremely powerful systems that include 2.5 shocks, coilovers, radius arms, 4-link systems, and other hardware so that your lifted Ram gets excellent handling and off-road performance. One of our favorite Ram lift kits is the Ram Cummins SuperLift 4" Lift Kit. SuperLift's 4" lift kit comes with front lift springs that add 4" of front ride height and larger rear blocks that give your Ram Cummins a clean look and fairly even stance. The SuperLift kit comes with a full set of shocks that give your Ram a great ride both on and off the road.
