How many lugs does a 2004 Chevy Trailblazer have?

Five lug nuts per wheel, for a total of 20 lugs on the vehicle.

In more detail, the 2004 TrailBlazer uses a standard five-lug wheel pattern on a 4.75-inch bolt circle, a setup shared by many GMT360 platform SUVs. This means each wheel is secured by five lug nuts, and with four wheels, the SUV has a total of twenty lugs when fully equipped.

Bolt pattern and lug count

The following points summarize the essential lug configuration for the 2004 TrailBlazer:

• Lug count per wheel: 5


• Bolt pattern (lug circle): 5 lugs on a 4.75-inch (120.65 mm) bolt circle


• Total lug nuts on the vehicle (four wheels): 20

These specifications reflect the factory standard for the model year and are common across the GMT360 family. If you’re replacing wheels or lug nuts, ensure you maintain this five-lug pattern and use the correct hardware to preserve safety and performance.

Notes on maintenance and compatibility

When swapping wheels or lug nuts, verify the exact pattern and consult the owner’s manual or a trusted parts guide. Always torque lug nuts to the manufacturer’s specified value and in the recommended sequence to avoid warping rims or uneven loading.

Bottom line

For a 2004 Chevy TrailBlazer, you’re looking at five lugs per wheel and twenty lugs total on the vehicle, secured by a 5x4.75-inch bolt pattern. This is the standard configuration for this model year and its GMT360 relatives.

For a 2001 – 2024 Chevy Trailblazer I or Trailblazer II, there are 24 pcs lug nuts to fasten the wheels. The bolt pattern is 6×127 or 6×139.7, so each wheel has 6 pcs lug nuts.

What is the bolt pattern on a 2004 Chevy?

The 2004 Chevy lug pattern is 6x139.7 mm (or 6x5.5 inches) for most light-duty trucks like the Silverado 1500 and Colorado. For models like the Chevrolet Tracker, the lug pattern is 5x139.7 mm (or 5x5.5 inches). It's important to check your specific vehicle model, as heavy-duty trucks have different patterns. 
Common 2004 Chevy lug patterns

• Silverado 1500 and Colorado: The 6-lug pattern is 6x139.7 mm (6x5.5 inches). 
• Suburban 1500: Most generations, including the 2004 model, use the 6x139.7 mm (6x5.5 inches) pattern. 
• Tracker: The 2004 Tracker uses a 5-lug pattern, which is 5x139.7 mm (5x5.5 inches). 

Important considerations

• Check your specific model: The lug pattern can vary between different models and trim levels. Always verify the correct pattern for your vehicle before purchasing new wheels. 
• Heavy-duty trucks: Heavy-duty models, such as the 2500HD and 3500HD, have different bolt patterns. For example, the Silverado 2500HD and 3500HD models before 2011 use an 8x165.1 mm pattern, while 2011 and newer models use an 8x180 mm pattern. 

Are all Chevy 6 lugs the same?

No, not all 6-lug Chevy wheels are the same; while many models use the common 6x5.5-inch or 6x139.7mm bolt pattern, other Chevy models use different patterns, and some vehicles have variations in center bore or offset that prevent them from being interchangeable. Always verify the exact specifications for your specific year and model, including the bolt pattern, center bore, and offset, before purchasing new wheels to ensure a proper fit. 
Common Chevy 6-lug patterns

• 6x5.5-inch / 6x139.7mm: This is the most common pattern, used on many full-size trucks and SUVs, including the Silverado 1500, and can be found in both metric and imperial measurements. 
• Other patterns: While less common, some models have different 6-lug patterns. For example, some Blazer models use a 6x120mm bolt pattern, which is different from the 6x139.7mm used on the Silverado. 

Key specifications to check

• Bolt pattern: The number of bolts and the diameter of the circle they form (e.g., 6x139.7mm). 
• Center bore: The diameter of the hole in the center of the wheel, which must match or be larger than the vehicle's hub to fit properly. 
• Offset: The distance from the wheel's mounting surface to the centerline of the wheel, which affects how the wheel sits in the wheel well. 

Why you should always check

• Incorrect fitment: Using wheels with the wrong bolt pattern, center bore, or offset can prevent the wheel from fitting correctly and may even cause damage to your vehicle. 
• Model and trim variations: Heavy-duty models, or even different trims on the same model, may have different requirements, so it's crucial to check the specifications for your specific vehicle. 
• Safety and performance: Ensuring the correct fit is essential for your safety and the vehicle's performance, as it affects handling and grip.
