What is the Chevy Silverado bolt pattern?
The bolt pattern for a Chevy Silverado depends on the model and generation. In practice, light-duty Silverado 1500 trucks commonly use a 6-lug pattern (6x139.7 mm or 6x5.5 inches), while heavy-duty Silverado 2500HD and 3500HD trucks use an 8-lug pattern (8x165.1 mm or 8x6.5 inches).
Beyond these main configurations, there are year-to-year and regional variations. Always verify your exact bolt pattern for your vehicle by checking the door jamb sticker, the owner's manual, or your VIN/build sheet. This ensures wheels, adapters, and accessories fit correctly and safely.
Common bolt patterns by Silverado model
The following patterns cover the configurations most commonly encountered on current and recent Silverado models. The numbers refer to lug count and the circle diameter in millimeters. If you are upgrading wheels, also verify center bore and thread pitch.
- Light-duty Silverado 1500 (most model years): 6x139.7 mm (6 on 5.5 inches)
- Heavy-duty Silverado 2500HD and 3500HD: 8x165.1 mm (8 on 6.5 inches)
These two patterns account for the vast majority of Silverado wheel compatibility, but there are exceptions, so always confirm with official sources for your exact year and trim.
How to verify your bolt pattern
To be sure you have the correct bolt pattern before purchasing wheels or adapters, use a straightforward verification method. The steps below help you confirm the correct fitment for your Silverado.
- Check the factory bolt pattern specification on the driver's door jamb sticker or in the owner's manual.
- Count the lug studs on the wheel hub and measure the bolt circle diameter. For example, a 6-lug pattern uses six studs arranged on a circle with a 139.7 mm diameter.
- Consult the VIN-specific build sheet or contact a dealer to verify the exact pattern, especially if the truck is older or modified.
With the pattern confirmed, you can source wheels confidently, while also paying attention to center bore size and lug nut/thread pitch to ensure proper hub alignment and secure mounting.
Summary
In the Silverado lineup, the bolt pattern is not one-size-fits-all. Light-duty 1500 models typically use 6x139.7 mm, while heavy-duty 2500HD and 3500HD trucks use 8x165.1 mm. Always verify for your exact year and trim, and check related factors like center bore and lug nut size when shopping for new wheels or adapters.
What is the bolt pattern on a Chevy Silverado 1500?
The Chevy Silverado 1500 uses a 6x139.7 mm (or 6x5.5 inch) bolt pattern, which has been consistent across all generations from 1999 to the present. Other specifications include an M14x1.5 thread size and a center bore of 78.1 mm.
- Bolt Pattern: 6x139.7 mm or 6x5.5 inches

Is 4x100 the same as 4x4 bolt pattern?
No, 4x100 is not the same as 4x4, because 4x4 is equal to 4x101.6mm, while 4x100 is a different, smaller measurement. The difference of 1.6mm may seem small, but it is enough that the two are not directly interchangeable, as they will not center correctly on the wheel hub.
- 4x4: This pattern is actually equal to 4x101.6mm.
- 4x100: This is a metric measurement, and it is smaller than the 4x4 (4x101.6mm) pattern.
- Interchangeability: Due to the difference in measurement, wheels with a 4x100 bolt pattern will not fit securely on a 4x4 (4x101.6mm) hub, and vice-versa. The lugs will not be centered correctly, which could lead to issues like lug or wheel failure.
- Use of adapters: It is possible to use adapters to bridge the gap between the two sizes, but this is a complex modification that requires careful installation and professional work.
