The 6.0L Powerstroke engine is a Ford diesel inline-six motor from 2003 to 2007. It replaced the 7.3L Powerstroke. Despite some criticism, it’s still a popular choice. It can tow heavy loads and accelerate quickly. Plus, through advancements in emissions control, it emits fewer pollutants than earlier diesel models under similar loading conditions.

6.0 powerstroke specification

The 6.0L Powerstroke has two families of engines. They share the same architecture and have differences depending on the vehicle. This article covers the specs for each family type and other features. Read on to learn more about this powerful Ford diesel option!

Engine Specifications

The 6.0L Powerstroke is a diesel engine created by Ford Motor Company. It’s a well-liked engine for Ford’s heavy-duty pickup trucks and has been around since the early 2000s.

Let’s take a look at the engine specs of the 6.0L Powerstroke and what makes it so unique:


The 6.0L Power Stroke was a V8 turbodiesel engine produced by Ford Motor Company. It was used in Ford Super Duty Trucks from 2003 to 2007. The machine had a displacement of 363 cubic inches (592cm3). Also, it weighed 1,380 pounds (615kg). It had an 88-mm bore and 98-mm stroke, with a compression ratio of 18:1.

The engine featured high-pressure common rail fuel injection. It had up to 30,000 psi pressure level and eight injectors. Depending on load requirements, these are sprayed up to eight times per cycle. This made it one of the most efficient diesel engines available.

When first released in 2004, the 6.0L Power Stroke could produce 325 horsepower at 3,300 pm and 560 pound-feet of torque at 2,000 rpm. However, revisions over time bumped the horsepower output slightly to 330 hp (245 kW)at 3,300 rpm and 570 lb-ft (780 Nm) torque at 2,000 rpm for the 2007 model year. This made it one of the most powerful diesel engines in heavy-duty trucks produced by Ford Motor Company during that period.

Compression Ratio

The 6.0L Powerstroke engine is designed with a compression ratio of 16.2:1. This is greater than other diesel engines. It yields complete combustion, more power, and less smoke. Higher compression also increases exhaust gas recirculation (EGR) and diesel emissions. This improved design yields fewer pollutants and more power at a lower RPM. It is resulting in a quieter, more fuel-efficient engine.

Bore and Stroke

Ford’s 6.0L Powerstroke engine is the first to feature a CGI engine block and heads. This material and Ford’s reduced turbo lag design give it strength and performance benefits.

The crankshaft has four main bearings, the camshaft has six-bolt caps, connecting rods are forged steel I-beam, and aluminum pistons have cast rings. The bore is 3.74 inches, and the stroke is 4.134 inches, for a displacement of 363 cubic inches (5.9 liters) and a 20:1 compression ratio. This provides plenty of power!

Firing Order

The 6.0L Powerstroke engine’s firing order is 1-2-7-3-4-5-6-8. This means the spark begins with Cylinder #1 in a particular sequence. This firing order allows for smoother power delivery and prevents vibrational forces from timing the crankshaft.

Correct spark plug spacing reduces heat build-up and ensures a powerful performance. The 6.0L Powerstroke has eight cylinders, and one firing cycle requires two crankshaft rotations. This cycle consists of intake, compression, expansion, and exhaust.

  • Cylinder 1 is on the front left (driver’s side).
  • Cylinder 2 is at the rear left side (driver side).
  • Cylinder 3 is at the rear right side (passenger side).
  • Cylinder 4 is at the rear center.
  • Cylinder 5 is at the front right side (passenger side).
  • Cylinder 6 is at the front center.
  • Cylinders 7 and 8 are found near the transmission bell housing at the back of the engine block.

Knowing the cylinder locations on the 6.0L Powerstroke makes it easier to diagnose and repair this strong diesel engine accurately!


The 6.0L Powerstroke engine has the same overhead valve design as the 7.3L Powerstroke. It consists of four valves and one camshaft per cylinder. A belt powered by the crankshaft drives the camshaft. The valves are cup-shaped and two per cylinder. They act as air nozzles when opened and closed. The exhaust valves are slightly bigger to create back pressure in the combustion chamber.

The cylinder heads have ports that deliver fuel and air directly. This improves emissions and performance, plus keeps out unwanted elements like oil, coolant, dust, and more. The valvetrain has been enhanced with two hydraulic roller lifters per cylinder. This increases surface area reduces noise and vibration, and improves sealing and durability.

Injection System

The 6.0L Powerstroke diesel engine uses a standard rail fuel injection system with a Bosch high-pressure fuel injection pump variation. The injectors are electronically controlled solenoid valves that execute multiple injections per cylinder.

The PCM (powertrain control module) uses signals from sensors like MAP (manifold absolute pressure), MAF (mass air flow), and engine RPM, among others monitored by the ECM, to command various parameters. This optimizes combustion for improved performance, sound quality, and lower emissions.

The injection system has two main parts – the Fuel Injection Control Module (FICM) and the High-Pressure Oil System (HPOS). The FICM uses 8 data channels to control up to 8 injectors, each with individual driver circuits for each cylinder power stroke injector. The HPOS pressurizes fuel from low-pressure pumps to the high-pressure injectors used.

The 6.0L Powerstroke has a ‘returnless’ fueling system design that eliminates an extra return line between the tank and the Common Fuel Rail (CFR) engine. The CFR has two piezo electric-type reciprocating injectors that feed fuel into each cylinder in precise amounts. It also helps manage the diesel particulate filter regeneration process. The CFR supply valve circuit is based on oil pressure feedback signals sent across 2 I-type monitoring solenoids. This is calibrated up to 4 thousand psi limits for reliable operation. This engine was produced from late 2004 until 2010, when EcoBoost replaced it. It will be remembered as a well-known commercial-grade workhorse truck diesel engine.

Fuel System

The 6.0L Powerstroke fuel system is made up of many parts. The High-Pressure Oil Pump produces up to 2800 psi of oil pressure, pushing fuel through the injectors and into the combustion chamber. The Low-Pressure Fuel Pump sends power from the tank to the injectors with an electronic pressure regulator.

The Fuel Injectors are electronically controlled and spray the right amounts of fuel at the correct times, as determined by the FICM (Fuel Injection Control Module). The High-Pressure Fuel Rails lubricate each cylinder during the peak duty cycle.

The ICP Sensor monitors injection control pressure and detects variations in engine speed or load. The IPR Valve and sensors control the variable vanes to regulate fuel rail pressures. Finally, the FICM monitors sensor signals from various motor components and adjusts injection timing for ideal performance. All these components work together to get the best from your 6.0L Powerstroke diesel engine.

Exhaust System

A 6.0L Powerstroke exhaust system consists of four parts:

  • The exhaust manifold bolts to the cylinder heads and funnels gases through one pipe.
  • Catalytic converters transform harmful components into water vapor and carbon dioxide.
  • Mufflers reduce noise from combustion.
  • Lastly, the tailpipe circulates air through an open end or valve.

Check for signs of wear or damage to keep the system in top condition. Additionally, replace the fuel filter regularly to avoid build-up. This will prevent further harm from sooty smoke expelled during start-up.

Transmission Specifications

The Ford 6.0L Powerstroke diesel has two transmission choices: the 5-speed TorqShift and the 6-speed TorqShift. The 5-speed is smoother and more fuel efficient. While the 6-speed offers higher performance and better acceleration.

Let’s inspect the transmission specs of this diesel engine:

Torque Converter

The 6.0L torque converter is made for peak engine performance and driveability. It is bigger than the 5.4L converter. Stall speed usually ranges from 2100-2500 rpm, depending on aftermarket changes. The housing has a torsional damper, cutting down driveline noise and discomfort.

The multi-disc lockup clutch brings efficient performance, quicker warmups, lower temperatures, and improved fuel economy during highway cruising. An improved stator/turbine shaft capture system reduces noise levels during converter lockup.

Input Shaft

The 6.0-liter Powerstroke diesel engine has a 10-spline input shaft to the torque converter. This shaft transmits power from the engine’s crankshaft to the transmission. The Ford 6.0L Powerstroke input shaft is 5 1/2 inches long and has a 0.625-inch diameter steel body. It has ten splines that attach to a 0.75-inch inside diameter converter hub. It also has dual needle bearings, which reduce friction during clutch engagements and disengagements. This helps protect the transmission from damage caused by excessive wear.

Output Shaft

The 6.0L Powerstroke engine’s output shaft is made from alloy steel, providing strength, wear resistance, and durability. It is 15.8″ long and has 19T splines. The rear seal is a rubber material for smooth shifting when the vehicle changes gears. An eight-hole bolt pilot pattern aligns the output shaft in the transmission case.

It’s lubricated with transmission fluid and cooled by integrated fins and increased speed. This keeps the components running at optimal temperature and assures proper operation of the output shaft.

Gear Ratios

The 6.0L Powerstroke engine has a manual five-speed “ZF S6-650” transmission. It has overdrive and clutchless shifting. It is a conventional shift design with no electronic controls or solenoids. It also has an integrated clutch booster.

The gear ratios are:

  • 1st – 3.03
  • 2nd – 1.62
  • 3rd – 1.00
  • 4th – 0.71
  • 5th – 0.58
  • Reverse – 3.20
  • Final Drive Ratio: 3.73

Transfer Case

The 6.0L Powerstroke truck has an NP246 electronic transfer case. It’s a full-time four-wheel drive system that powers all four wheels simultaneously. It has a rotary switch between 2WD, Auto 4WD, 4 High, and 4 Low.

  • 2WD allows the full power of the engine to go to the rear wheels until slippage happens. Then, part of the torque goes to the front axle.
  • Auto 4WD splits the power evenly between the front and rear axles. This gives better traction and stability.
  • 4 High is a 4-wheel drive with automatic engagement when slippage is detected. It also has a front differential lockup.
  • 4 Low increases torque up to 100% and drastically slows vehicle speed. It should only be used for extreme off-road terrain, as it puts a lot of weight onto all four axles from the engine braking effect.

Drivetrain Specifications

The 6.0L Powerstroke engine is a V8 diesel-powered motor. It is made for Ford Super Duty pickups and Econoline vans. This engine has 32 valves and an aluminum cylinder head. The block is made of cast iron.

This section will cover its transmission, axles, and other vital components.

Axle Shafts

Axle Shafts are a dynamic drivetrain component. You get increased strength, weight savings, and better control with the proper setup.

For 6.0L Powerstroke, there are three standard axle shafts:

  1. Dana 60 Я-Stamped Axles – top quality; heat treated; 41-spline; 35% better than OEM.
  2. Dana Super 60 Axles – 31% improvement; larger spline; lightweight.
  3. Ford 10.25″ YS ОЕ replacement axles – cast from high-strength alloy steel; 20 splines; no extra weight.

For higher performance, aftermarket axle shafts can be purchased. But, these should only be replaced twice before they need professional service due to internal wear caused by strain or friction.


The 6.0L Powerstroke engine uses a 10.25-inch rear differential. It gives greater torque and stability. This helps the power reach all four wheels more efficiently and provides better traction.

Dana/Spicer makes the axle shafts for quality. Plus, a power divider reduces torque to each wheel when cornering. The carrier bearing is improved for durability and performance.

  • The ring and pinion are more robust than before. This provides more clamp load on both housing ends.
  • The pinion bearings are upgraded for more strength and to handle higher loads.
  • An optional locker is available. It eliminates wheel slip and improves split traction. This reduces wear on drivetrain components.

Gear Ratios

Gear ratios for the 6.0L Powerstroke vary by model year and transmission type. It was available with either the 5R110W TorqShift 5-speed or an E4OD 4-speed automatic.

Manual transmissions had three gear ratio variations:

  • 4.11:1 x 0.84
  • 4.30:1 x 0.78
  • 4.88:1 x 0.71

The TorqShift 5-speed automatic was released in 2003. It had two variants – one with Low Gear and one without. In 2006, 2004-2005 models got a refreshed PCM design. This changed the shift points and other parameters. These two boxes usually had a 3.31 final drive ratio. Lower axle ratios were offered for customer custom orders and fleet trucks. These had an extra deep LowGear. 2006-2007 models got a new PCM recalibration. This gave better control of shift times and more locking force. This reduced clutch slippage and improved fuel economy.

The E4OD 4-speed transmission debuted in 1988. Earlier versions didn’t include electronic controls and overdrive gearing. Controls were wired via a throttle position sensor and mechanical linkage. Later versions used Electronic Throttle Body Control measurements. They have different architecture and components, except for output shaft upgrades if needed.


We’ve reached the end of our Ford 6.0L Powerstroke specs review. This rugged diesel engine is built carefully and tested to its full potential. It has advanced tech and components, making it a reliable power source. You can use its features for more efficiency, reliability, and energy.

Its power-to-weight ratio, low emissions, and long lifespan make it a wise investment. You’ll have peace of mind, knowing you’ll stay confidently on the road.
