What is the Chevy Blazer bolt pattern?
The bolt pattern depends on the Blazer’s generation. The modern 2020-and-newer Blazer uses a 6-lug pattern (6x120.65 mm), while older K5/K-series Blazers used a 5-lug pattern (5x127 mm).
Current generation bolt pattern (2020–present)
Details for the latest Chevrolet Blazer, which shares parts with other GM midsize SUVs.
- Bolt pattern: 6x120.65 mm (6 on 5.0 inches)
- Center bore: 66.0 mm
- Notes: Most OEM and aftermarket wheels designed for 6x120.65 mm with a 66.0 mm center bore will fit, though hub-centric rings may be needed for some wheels
In practice, verify wheel compatibility for your exact trim and year, as some editions or aftermarket parts can vary slightly in hub requirements.
Older generations bolt pattern
For the Blazer models from the GMT400 era and earlier (notably the K5 and other early Blazers), the wheel mounting configuration differs from the modern model.
- Bolt pattern: 5x127 mm (5 on 5 inches)
Wheels and adapters for older Blazers must match 5x127 mm, and you should confirm center bore and offset with your specific year and model before purchasing.
Summary
To recap, the 2020–present Chevy Blazer uses a 6x120.65 mm bolt pattern with a 66.0 mm center bore. Older Blazer generations, such as the K5 and other GMT400-era models, use a 5x127 mm bolt pattern. Always verify the exact specs for your vehicle’s year, trim, and any aftermarket parts before buying wheels or adapters.
