2004 Chevy Silverado Bolt Pattern

The
bolt pattern for any Chevy
Silverado between 2003 and 2007, including the 2004 Silverado, is 6x5.5
But what does that figure represent? Basically, every bolt pattern can be expressed in the following way:
# of bolts x diameter of the circle they form
Therefore, the 2004 Silverado’s 6x5.5 bolt pattern means each wheel features six bolts forming a circle that’s 5.5 inches in diameter. Knowing this measurement is key to switching up your truck’s wheels—but there are a few other figures to know, including your wheel’s offset, stud size, center bore, and more. Check out the numbers below:
  • Factory wheel size: 17” to 18” 
  • Stud size: 14 mm x 1.5 (M14 x 1.5) 
  • Offset: 4 to 25 mm (depending on trim level)
  • Center bore: 78.1 mm
  • Wheel tightening torque: 190 Nm

How to measure your Chevy Silverado bolt pattern

Now that you’ve got your Chevy Silverado bolt pattern down, you’re ready to switch out your rims and upgrade your wheels! But if you’re a perfectionist (like us) you may be tempted to check those measurements for yourself. Don’t worry—we’ve got you covered. 
To measure your Chevy Silverado’s bolt pattern yourself, all you’ll need is a measuring tape (even a simple ruler will do!). Start by selecting any bolt, and measure from its center to the center of the opposite bolt. Because your truck has six bolts, you can measure straight across, from center to center.
The measurement you get represents the diameter of the circle. Put that number together with the number of bolts your wheel has, and you’ve got your bolt pattern!
