First, you can check the drivers side of the valve cover at the estimated horsepower.

Q: How do you find out if your Cummins is a 2004.5 or a 2004?Ī: There are two ways. Some are completely off the wall and can even catch us off guard at times, but many others are fairly routine, so we thought we'd post some of the most popular questions that can hopefully be a good resource for you. We get a lot of calls and e-mails each day with various product, vehicle, and installation questions. Products in this section are designed to work on 20 model year Dodge trucks equipped with the 5.9L Dodge Cummins unless otherwise noted. If you need help with your decision don't hesitate to call. If you are still unsure call your local Dodge dealer with the last 8 #'s of your VIN and they can clarify it for you.

2004's will show a horsepower rating of 305. On a 2004.5 the tag will show a torque rating of 600 or a horsepower rating of 325. One way to check is to locate the red or silver tag on the driver's side of your block.

Different injectors, different turbos, different exhaust systems (2004.5 trucks have full 4" exhausts and catalytic converters), different valve bodies in the transmission etc. NOTE: For those of you with 2004 model year trucks, it is important to understand that there are significant differences between a 2004 and a 2004.5. Whatever your goal is for your truck, whether it's big horsepower or better handling, we can help you out with name brands like Carli Suspension, BD Diesel Performance, Industrial Injection, Valair Clutch, Dynomite Diesel, ISSPRO Gauges, FASS Fuel Systems, Mads Electronics Smarty Tuner, Edge, MBRP Exhaust and much much more. The addition of the right tuner (our choice would be Smarty), a decent set of injectors, an upgraded turbo, some transmission modifications, some gauges to keep an eye on things, and these trucks will easily slip into the 500 RWHP range. Most Cummins enthusiasts would agree that this new system is easier to get big horsepower from and all without sacrificing diesel fuel economy. Dodge ditched the troublesome VP44 in favor of the more reliable Bosch CP3 injection pump, capable of supplying fuel at up to 30,000 PSI to the rail. The 2003 model year was the beginning of a new era for the Cummins Turbo Diesel.
