The year 2007 was a big year for Dodge and its close partner Cummins. Due to tightening emissions standards, a new engine design was required, and they would stray from the 5.9L displacement that they had carried since 1989 in favor of a 6.7L with a host of new features. For starters, this new engine would come with the highest factory flywheel power rating to date, a whopping 350 horsepower and 650 lb.-ft of torque. Further, Ram finally let go of their overworked four speed automatic transmissions in favor of a six speed by means of the 68RFE in pickups and Aisin in cab and chassis models. In order to keep up with the demands of higher horsepower and the efforts to reduce emissions, a Holset Variable Geometry Turbo (VGT) was introduced to aid in low end spool up. With all of these factory upgrades, what more could you ask for? How about better mileage, more power and increased driveability? That's where we come in!


While we offer a vast assortment of factory (stock) replacement parts for your Dodge, we are indeed Diesel Power Products and offer a ton of parts to increase the performance of your 2007.5, 2008, or 2009 Cummins. Maybe you’re just getting started and looking to replace the restrictive air filter system with a high flowing cold air intake. Or possibly you’ve heard about people adding a “chip” or “programmer” to net some extra MPG’s and even added power. Sure, we have you covered there. Or maybe you’re like us and got those upgrades out of the way long ago but ready to make some serious horsepower and interested in upgraded injectors, a bigger turbo (or maybe a set of compounds), higher displacement CP3 injection pump, and a built transmission to handle all of it. You bet we’ve got all of those parts and can discuss your goals with you and get a plan in motion.


Did you know that one of the most popular upgrades to your 3rd Gen Ram is to the steering and suspension? On one hand, there are the “fix-it” parts that cure common issues, such as sloppy steering, by using better aftermarket parts such as our line of Red-Head Steering Gear Boxes. On the other hand, there are parts to increase the performance of your suspension like our offerings from Carli Suspension. Wouldn’t it be nice if your truck didn’t buck you out of the seat when you hit a set of railroad tracks or bounce the truck into the ditch going down a washboard dirt road? Good news, we have a massive assortment of upgrades that will make you enjoy driving it again and won’t touch the payload capacity of the truck. Or maybe your #1 objective is build a truck that more resembles a Baja 1000 race truck. Cool, we’ve got you covered there, too!

Overall, Diesel Power Products carries everything you need for your 6.7L including AirDog and FASS Fuel Systems, Diamond Eye and MBRP Exhaust Systems, Fleece Cheetah Turbos and CP3 Injection Pumps, ISSPRO EV2 and Autometer Factory Match Gauges, Dynomite Diesel Injectors, BD Turbos and Transmission Upgrades, Mag-Hytec Differential Covers, Edge and Smarty Programmers, South Bend and Valair Clutches, Carli Suspension, Snow Performance Water/Methanol Injection systems and much, MUCH more. All of these parts choices can be overwhelming, if you need help give us a call and we will be more than happy to answer your questions.

We get a lot of calls and e-mails each day with various product, vehicle, and installation questions. 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.

Q: Does your HE351VE (Variable Geometry Turbo / VGT found on 6.7L Cummins) come with an actuator, and if so, is it pre-calibrated?
A: Yes, all HE351VE's we sell come with an actuator, and is pre-calibrated, ready for installation.

Q: What is the difference between the 2007 and the 2007.5 Cummins?
A: In 2007.5 Ram introduced an emissions controlled engine that was the 6.7L in comparison to the 5.9L they had in 2007. The 6.7L has higher power ratings and came equipped with a factory EGR (Exhaust Gas Recirculation) system and DPF (Diesel Particulate Filter) in the exhaust. Both were done in response to heightened EPA regulations that went into effect January 1st, 2007.

Q: Will a DPF (Diesel Particulate Filter) back system provide more sound to my truck?
A: Generally speaking no, the emissions equipment upstream will still act as a muffler. However, that doesn't mean installation will not help in other areas by improving exhaust flow. While minor, the benefits are noticeable, plus an aftermarket exhaust looks way better than the stock exhaust.

Q: Will an aftermarket "2nd Gen" turbo swap kit on my 6.7 Cummins remove the factory exhaust brake?
A: Yes, the stock exhaust brake is part of the factory turbo. When removing the factory turbo in favor of a non-VGT (Variable Geometry Turbo), the factory exhaust brake function is removed, as well.

Q: Do I need the Extreme Duty Red-Head Gear Box, or the regular unit?
A: The Extreme Duty is built for those running exceptionally large tires, such a a very wide 35" or a 37" or larger diameter. This model would also be a good idea for those vehicles whom regularly see off road use.

Q. Why does it sound like my transmission rattles after I installed a new clutch.
A. That noise that you are hearing is called gear rollover noise. It is evident in all transmissions, which is the reason the factory originally installs dual mass flywheel clutches, as they will cut down on that noise. The G56 is especially bad because it has a large aluminum case that acts as a megaphone. It is a completely normal condition, but can be helped. We typically recommend filling the fluid up to the fill plug in the transmission, then pulling the shift tower and putting one extra quart in. That will significantly cut down on the gear rollover noise.

Q: I'm looking at an exhaust kit on your website, but it doesn't state which cab and bed configuration it fits, will this fit my application?
A: In most cases, unless it is specifically stated as fitting a certain configuration, all exhaust kits on our website will fit all cab and bed lengths. Further, most kits will not fit cab and chassis applications unless otherwise noted.

Q: I'm looking at this 5" (or other) exhaust kit, but my truck only has a 4" exhaust now. Does this 5" exhaust include an adapter / reducer?
A: Yes, the exhaust systems we sell will adapt down to fit the application at the designated starting point (turbo back, cat back, DPF back, etc.) for a hassle free installation.

Q: What are EGT's?
A: EGT stands for Exhaust Gas Temperature, which is the temperature of the exhaust leaving your engine. This measurement is typically measured before the turbo to ensure you are not overheating components. For most applications, we recommend not exceeding 1300 degrees.

Q: Do you offer smoke and lope tunes with any of your preloaded EFILive AutoCal options?
A: No we do not. In short, both smoke and lope tunes create these results at the expense of the overall reliability of your engine. The tuning companies we have chosen to partner with are top notch and are most intested in creating increased power, fuel economy, and overall drivability. We at Diesel Power Products invest a substantial amount of time and effort to ensure that the products we recommend are in the best overall interests of our customers and their trucks, and unfortunately, these types of tunes do not align with that overall goal.

If you've got a question about your Cummins, feel free to give us a call at 888-99-DIESEL and we would be happy to assist.
