What is the bolt pattern on a 2004 Ford dually?
The bolt pattern for a 2004 Ford dually (F-250/F-350 Super Duty with dual rear wheels) is 8 lug on a 170 mm bolt circle, commonly written as 8x170.
For readers navigating wheel replacements, repairs, or upgrades, this article explains what that means for compatibility, how to verify the pattern on your vehicle, and common considerations when sourcing wheels and accessories.
Bolt pattern specifics for the 2004 Ford dually
The key facts you need to know about lug arrangement, circle diameter, and what models used this pattern are below.
Before you buy new wheels or spacers, review these details to confirm compatibility.
- Lug count: 8
- Bolt circle diameter: 170 mm (approximately 6.69 inches)
- Primary vehicle applications: Ford F-250 and F-350 Super Duty (DRW/dually configurations) around the 2004 model year
- Center bore: Varies by wheel; factory Ford wheels commonly use a hub-centric bore, while aftermarket wheels may require rings or adapter spacers to fit properly
When replacing wheels, the bolt pattern and center bore determine whether a wheel can seat properly and center on the hub. Always verify with the wheel manufacturer or consult your dealer mechanic for confirmation.
Why the pattern matters and how to verify
Understanding the eight-lug, 170 mm pattern helps ensure you choose wheels that align with the hub, brake caliper clearance, and overall vehicle geometry. DRW models can have slightly different offset and hub dimensions compared with single-wheel variants, which can affect fitment and tire clearances.
How to verify on your own vehicle
To confirm the bolt pattern on your specific truck, you can:
- Count the lug studs on the wheel hub (must be eight).
- Measure the diameter across the lug holes to confirm approximately 170 mm (6.69 inches).
- Consult the owner’s manual, VIN-specific specs, or Ford's official parts database for your exact build. If buying aftermarket wheels, verify center bore and hub-centricity with the vendor.
With this information, you can be confident you’re selecting wheels that will fit your 2004 Ford dually without clearance issues or misalignment.

For a 2004 Ford dually, the standard wheel bolt pattern is 8x170, eight lugs on a 170 mm circle. This pattern is typical of the F-250 and F-350 Super Duty DRW configurations of that era.

What is the bolt pattern on a Ford dually wheel?
Ford dually bolt patterns vary by year, but recent models (2005-present) use an 8x200mm pattern for dually (dual rear wheel) trucks. Older dually models (1999-2004) used an 8x170mm pattern.
Bolt patterns by year
- 2005 - Present: 8x200mm
- 1999 - 2004: 8x170mm

- Wheel fitment: Knowing the correct bolt pattern is crucial for ensuring wheels will fit correctly. A wrong bolt pattern will prevent a wheel from mounting onto the hub.
- Model year: The bolt pattern changes between different generations, so it is essential to confirm the specific year of your truck. For example, a 2005 model will have a different bolt pattern than a 2004 model, even if they look similar.
