Best 2003-2007 Ford F250 / F350 6.0L Powerstroke Parts & Accessories

2003-2007 Ford 6.0L Powerstroke Engine Upgrades

Assuming your 6.0L Powerstroke is bulletproofed and ready to go (and if it's not, that's probably where you should start), the first place most folks start with their 6.0L Powerstroke build is by adding power and torque. While the 6.0L Powerstroke had good pull at the time, it's definitely fallen behind newer Powerstroke models. The best way to keep up is with our 6.0L Powerstroke Engine Upgrades. The engine upgrades for 6.0L Powerstrokes can add huge levels of horsepower and torque so that your 6.0L Super Duty can keep up with the best of them on the street, at the sled pull, or out on the trail. One of the most effective ways to get your 6.0L Powerstroke churning out a lot more power is with our 6.0L Powerstroke Tuners & Monitors. An aftermarket tuner comes with a new software for your 6.0L Super Duty's PCM that changes key parameters of your F250 or F350's engine management system so that your 6.0L Powerstroke throws down a ton more horesepower and torque than stock. A new tune increases boost pressure, adjusts fueling, and changes transmission function so that your 6.0L Powerstroke feels like an entirely new truck. One of our most popular tuners for the 6.0L Super Dutys is the Ford Powerstroke Edge CTS3, which comes jam-packed with powerful performance tunes and features a massive color touchscreen display that makes it one of the most effective monitoring systems on the market.

Even though tuning can get your 6.0L Powerstroke huge amounts of power, they are pretty pricey, and all that power may not be a good thing if your 6.0L Super Duty has seen better days. Adding a 6.0L Powerstroke Cold Air Intake to your Super Duty will give your truck a nice bump in horsepower and torque without breaking your bank and without a bunch of hassles. Cold air intake kits are extremely easy to install and come with everything you need to get them up and running on your F250 or F350 build. One of our most popular intake kits is the 6.0L Powerstroke S&B Oiled Cold Air Intake. The S&B intake comes with a high-flow air filter, complete air box, and full set of inlet tubing that completely replaces the OEM intake system and gets you more horsepower, more torque, and better throttle response all in one place. S&B's intake features a high-quality construction and highly efficient design that makes it one of the most effective intake systems on the market.

2003-2007 Ford 6.0L Powerstroke Leveling Kits

A big issue with a bone-stock 6.0L Powerstroke is its factory stance and ride height, and they have a ton of front rake with a stinkbug look and no clearance for big tires. If you want to fix both problems all in one place, then you're going to need one of our 6.0L Powerstroke Leveling Kits. These 6.0L Super Duty leveling kits add just enough ride height to give your F250 or F350 a clean, leveled stance while also adding enough clearance to fit on bigger wheel and tire combinations than stock. We have a variety of 6.0L Super Duty leveling kits available that can fit any budget or application. We carry everything from basic leveling spacers to complete suspension systems that feature powerful shocks, coilovers, and other suspension hardware so that your 6.0L can tackle tough challenges both on and off the beaten path. One one of our most popular 6.0L Super Duty leveling kits is the Carli 2.5" Leveling Kit with Signature Shocks. Carli's leveling kit adds 2.5" of ride height through a set of progressive coil springs that are paired with a set of Carli Signature Series front shocks that give your Super Duty build excellent on-road ride and off-road performance. The kit also includes brake line brackets and caster shims so that you avoid overstretching your brake lines and alignment issues.

2003-2007 Ford 6.0L Powerstroke Lift Kits

Even though a leveling kit will add a clean look and let you fit on slightly bigger tires, if you really want to go big with your tire choice, you're going to need a bunch more ride height. That's where our 6.0L Powerstroke Lift Kits come in. These 6.0L Super Duty lift kits add more ride height to both the front and rear of your truck, giving your F250 or F350 a big look and the ability to mount up extremely big wheels and tires. We have lift kits in a variety of different ride heights so that you can find the perfect amount of lift for the look you want and the tires you want to clear. We carry lift kits to fit any budget, from wallet-friendly systems that only include core lift components to high-performance lift kits that come with 2.5 shocks, coilovers, radius arms, 4-link kits, and other suspension hardware that can have your 6.0L handling and performing at its very best. 

2003-2007 Ford 6.0L Powerstroke Wheels & Tires

How reliable are the engine and transmission on the 2003-2007 Ford Super Duty models?

The 6.0L Powerstroke Turbo Diesel engine in this generation has mixed reliability. The 5-speed TorqShift automatic transmission is generally reliable, but the 6.0L Powerstroke is known for issues like head gasket failures, EGR cooler failures, and oil cooler problems if not properly maintained. At this point, though, the process to “bulletproof” the 6.0L is well documented, so it’s still a powerplant worth running, once the right upgrades have been made.

What are the fuel economy estimates for the 2003-2007 Ford F-250 and F-350?

Drivers of the 6.0L Powerstroke typically report fuel economy between 12-17 MPG, depending on load and driving conditions. Highway driving tends to yield the best results, while towing or city driving can reduce fuel efficiency significantly.

What lift kit options are available for the 2003-2007 Ford F-250 and F-350?

There are a variety of lift kit options available, ranging from 2.5-inch leveling kits to 6-inch suspension lifts from brands like Carli, Rough Country, SuperLift, and Superlift. These kits improve ground clearance and allow for larger tires.

Are there any known weaknesses in the engine or transmission of the 2003-2007 models?

The 6.0L Powerstroke responds well to modifications once it’s been “bulletproofed”, and power gains of 75-100 horsepower can be achieved with diesel tuners, exhaust systems, and cold air intakes. However, anyone choosing the 6.0 Powerstroke needs to accept they’ll have to address engine reliability before adding any power upgrades.
