Are All Chevy 6 Lug Patterns the Same?

Chevy Silverado Rim

If you’re preparing to upgrade the wheels on your Chevy, or need to repair one that was damaged on the Los Banos roads, it’s important to be aware of the wide range of varying wheel sizes and configurations. Understanding some basic information about lug patterns ensures that you select the right wheel to match your vehicle. Are all Chevy 6-lug patterns the same? 

The answer is no – all Chevy 6-lug wheels are not created equal. Different sizes and bolt patterns exist across various models that Chevy has released in the past. The most common Chevy 6-lug bolt pattern that you’ll find on the highest number of vehicles on Modesto roads, is the 5-127 metric. Between 1973 and 1998, this was the lug used on most Chevy full-size truck models. 



What is the Bolt Pattern for a Chevy 6-Lug? 

One of the most common 6-lug patterns is the Chevy 6-lug. This design has been recycled repeatedly over the years. There’s a high chance that if you drive a Chevy, your model has this wheel configuration. The most common model years to use the Chevy 6-lug include: 

  • Chevrolet Colorado – 2004-2012
  • Chevrolet Express Full-Size Van – 1996-Current
  • Chevrolet Avalanche – 2003-2013
  • Chevrolet Blazer (2WD) – 1969-1999
  • Chevrolet Kodiak Truck (C4500/C5500/C6500) – 2003-Current
  • Chevrolet K5 Blazer (4WD) – 1969-1991
  • Chevrolet C10/K10 Pickup – 1960-1998
  • Chevrolet C10 Suburban – 1960-1991
  • Chevrolet Impala SS – 1994-1996
  • Chevrolet Caprice – 1971-1996

Identifying Your Chevy Lug Nut

Different types of lug nuts exist that fit different makes, models, and wheels. You must understand how to identify your Chevy lug nut so you install the right variety. This ensures your wheels stay on securely and lower your chances of mechanical failure while you drive. The thread size is the diameter, which is the measurement of the studs attached to your rotor where you mount the tires. When you see the term “pitch” it’s describing the distance in millimeters between threads. Finally, the “seat type” describes the point of contact between the surface of your wheels and the lug nuts. The most common seat types are: 

  • Ball seat
  • Mag seat
  • Tapered seat

Do Chevrolet and GMC Use the Same Bolt Pattern? 

The answer to this question is yes. Chevrolet exists under the GMC umbrella, and many of their vehicles are nearly carbon copies of one another (Silverado and Denali) with small differences in the feature or luxury department.
