Comprehensive 6.4L Powerstroke Specifications
2008-2010 Ford SuperDuty 6.4L Powerstroke Diesel Specs
The 6.4L Powerstroke was introduced in 2008 to Ford’s Superduty lineup. A new body style accompanied the motor change, as well as significant interior improvements that made these trucks more luxurious and more comfortable. After the 6.0L Powerstroke stint, Ford Diesel owners were ready for something new and hopefully, something more reliable. Would the 6.4L Powerstroke be any better? We’ll give you everything you need to know about Ford’s 2008-2010 Superduty Diesel offering. Below you’ll find detailed 6.4L Powerstroke specifications, features, and tow capacity.
The 6.4L Powerstroke was very impressive for the time, offering 350 horsepower and 650 lb/ft of torque and a max tow capacity of 24,600 lbs (2010 F-450). It’s partnered with a 5-speed automatic TorqShift transmission or an available 6-speed manual transmission. The 6.4L Powerstroke also featured a twin turbocharger set-up, a new DPF emissions system, and other unique specs. For a comprehensive overview of 6.4 Powerstroke specs, just take a look at the chart below.

Is the 6.4L Powerstroke better Than the 6.0?
Would Ford’s 6.4L Powerstroke become any better than the 6.0L Powerstroke? Not by much. While I do believe the 6.4L Powerstroke engine is a beefier, more reliable engine, the factory emissions devices found on these trucks greatly decrease their reliability and fuel economy. Emissions devices aren’t the only issue either. Other common problems include cracked radiators and cracking exhaust up-pipes. Unfortunately, servicing these trucks is also very expensive. They were designed to be worked on with the cab off. This results in very high labor rates.
Unfortunately, the 6.4L Powerstroke proved to be unreliable, and Ford abandoned the 6.4L engine and their partnership with International in 2011. Starting in 2011, Ford released their own 6.7L Powerstroke engine, built in-house. It ended up being the engine Ford had hoped for. A much-improved 6.7L Powerstroke engine is still used as I’m writing this, in 2020.
The First Twin-Turbocharger Set-up From the Factory
While the reliability of a 6.4L is questionable, these trucks feature some exciting upgrades that make attaining big power very easy. What is the most notable 6.4l Powerstroke feature? The twin sequential turbo set-up. This turbocharger set-up reduces turbo lag and improves performance. Even just the addition of a tuner or programmer can push the 6.4L Powerstroke to 550-600 horsepower. The 6.4 engine features a significantly stronger cylinder head design than the previous 6.0 too.

New Emissions System: The DPF
While the 6.4L Powerstroke offered many improvements over the 6.0, many new problems arose. Many of these issues are attributed to new emissions systems. The 6.4L Powerstroke’s emission system features a DPF, or diesel particulate system. Unlike modern DPFs that use direct fuel injection into the exhaust stream, the 6.4L Powerstroke’s DPF system allows fuel to be released during the exhaust stroke. Diesel is then routed through the exhaust manifold and other crucial components until it reaches the exhaust stream. Needless to say, this is a very poorly designed system. Fuel dilution in engine oil is commonplace with the 6.4L Powerstroke. It can lead to major problems like cylinder washing. This is just one of the 6.4L Powerstroke problems.
EGR systems are used to greatly reduce nitrogen oxide release from the tailpipe. While they help the environment, they’re often a headache for diesel owners. Remember how problematic the 6.0L Powerstroke’s EGR system was? Well, the 6.4L Powerstroke has more than just the standard EGR Valve and EGR Cooler. Two EGR Coolers are used on the 6.4L Powerstroke. That’s right, two!
Lastly, the 6.4L Powerstroke is equipped with a diesel oxidation catalyst. Most diesels feature this component, as it is the diesel version of a catalytic converter. In the DOC an oxidation reaction occurs that turns Hydrocarbons and carbon monoxide into water vapor and carbon dioxide.

6.4L Tow capacity varies according to model year and model specifications. Max conventional and fifth-wheel tow capacity are listed in the chart below. Before you tow, make sure you check your owners manual or contact Ford directly to determine your exact capacities. It’s always good to be cautious and keep any loads below your truck’s max tow capacity or payload.
6.4L Powerstroke Max Towing Specifications
|5th-Wheel Tow Capacity:||16,500 lbs||18,800 lbs||24,600 lbs|
|Conventional Tow Capacity:||12,500 lbs||15,000 lbs||16,000 lbs|
|GCWR:||23,000 lbs||26,000 lbs||33,000 lbs|
|GVWR:||10,000 lbs||13,000 lbs||14,500 lbs|
|Payload:||3220 lbs||5730 lbs||6180 lbs|
