Chevy uses various sizes of 6 lug bolt patterns on their cars. It’s easier and time saving to find the exact replacement parts. If your Chevy car needs a wheel with 6 lug bolt pattern, you won’t have to suffer much.
Are all Chevy 6 lug bolt patterns the same? Yes, all Chevy 6 lug bolt patterns are the same, making it easier to find and quicker to install without making new drills or modifications. For safety, you should measure the lug number, its diameter and pattern physically to ensure a perfect fit.
Article Summary
Are All Chevy 6 Lug Bolt Patterns the Same?
Chevy usually uses a 5.5 inch standard, 6 lug and medium offset bolt pattern for their silverado pickup trucks and SUVs. However, the 6 lug Chevys, use the same bolt pattern. If you have two 6-lug Chevy, they have the same bolt pattern. Chevy fixed the problems of matching bolt pattern.
However, some older Chevy models like the 1500 4×4 pickup trucks used 5.5 inch bolt pattern which is another common pattern for Chevy vehicles.
Role of A 6-Lug Bolt Pattern
The 6-lug bolt pattern contains 6 equally spaced holes that are meticulously arranged on the hub face of the vehicle. It ensures accurate alignment between the hub and wheel and provides optimal stability and performance. The 6-lug bolt pattern is widely used on various types of vehicles including SUVs and trucks.
This design helps attach the wheels to the vehicles securely and works with certain types of wheels to ensure a safe connection.
Chevy Vehicle That Uses 6 Lug Bolt Pattern
Chevy recycled 6 lug patterns frequently throughout the years. So if you have Chevy, possibly its wheel has this 6-lug wheel configuration. Below are some common Chevy models that use 6-lug bolts:
- Colorado- 2004 to 2012
- Avalanche- 2003 to 2013
- Express Full-Size Van- 1966 to current
- K5 Blazer- 1969 to 1991
- Blazer- 1969 to 1999
- Impala SS- 1994 to 1996
- Caprice- 1971 to 1996
- Kodiak Truck- 2003 to Current
- C10 Suburban 1960 to 1991
How To Identify Chevy Lug Nut?
The design of the lug nuts varies largely depending on the car model and make. So it’s crucial to understand the Chevy lug nut identifying process so you can install the right type. Otherwise, the wrong wheel won’t stay securely on your vehicle and will increase the risk of mechanical failure while driving.
To identify the lug nut, you should know about thread size, pitch, and seat type. the thread size is a stud’s measurement that is attached to the rotor where need to set the tire. A pitch is a distance between threads that measure in millimeters.
The seat type is a contact point between the wheel’s surface and lug nuts. The mostly used seat types are tapered seats, mag seats, and ball seats.
How To Measure the Chevy 6-Lug Bolt Pattern?
Firstly, counts the lugs and you’ll possibly have 4, 5, or 6 lugs on the Chevy vehicle. Then measure the lug’s diameter.
Odd-numbered lug patterns are more difficult to measure than even ones. To find out the measurement of the bolt pattern, start measuring from one bolt’s center to the opposite bolt’s center. Then measure the hole between the lugs that set diagonally. You can take this measurement in inches or millimeters.
After combining both measurements, you’ll have something like 5×180 or 6×139.7. Compare it with your vehicle to determine if the wheel will fit or not. If you are still confused, consult with an expert mechanic.
Types of Bolt Patterns
The bolt pattern’s design varies largely depending on the car’s make and model. Below are the most common type of lug bolt patterns:
4-Lug Bolt Pattern
This lug bolt pattern uses 4 bolts to keep the wheel secure to a vehicle and mostly use on small cars and SUVs. It is also used on hatchbacks, sedans, and various compact cars.
4 lug bolt pattern ensures optimum stability and dependable fastening to keep the wheel in the center of the car’s hub. The manufacturer intended four bolt patterns for lightweight vehicles that require less torque handling abilities.
5-Lug Bolt Pattern
It consists of 5 equally spaced bots that keep the wheel secure to the vehicle’s hub. The five-bolt pattern provides reliable stability of the wheel to make driving safer. However, it’s a bit difficult to determine the measurement of the 5-lug bolt pattern because of its bolts number. To make the job easier, measure the center-to-center distance between two lugs.
6-Lug Bolt Pattern
This standardized design use 6 bolts to securely attach the wheel to the vehicle. 6 lug bolt pattern is broadly used in Chevy vehicles and is popular for strength and reliability. To find out if your vehicle has a 6-bolt pattern, measure the center-to-center distance between one lug and its opposite lug.
This method will provide you with accurate results. Alternatively, you can measure the distance of the outside edge between two studs that cross directly. Though it’s an effective measurement system, mechanics don’t use it widely to measure the lug center distance.
8-Lug Bolt Pattern
It’s a broadly used log pattern that accommodates 8 lug bolts to secure the wheel to the vehicle. In this bolt pattern, 8 lug bolts are placed equally around the revolution’s circumference to ensure proper alignment and stability.
The holes are drilled accurately so the 8-lug wheel’s bolt fits perfectly. Eight bolt patterns are usually used on heavy-duty SUVs, passenger cars, and trucks to ensure superior durability and strength required for improved towing capacity and heavy load-carrying ability.
This lug pattern also ensures a secure connection between the car’s hub and wheel and minimizes looseness or vibration while driving.

FAQs
Are 6×139 7 and 6×5.5 the same pattern?
Yes, both bolt patterns are the same. However, the difference is that 6×139.7 is written in the metric method while 6×5.5 is written in standard measurement. Both of these bolt patterns can be interchanged.
Are all Chevy lug nuts the same size?
No, all Chevy nuts aren’t the same size. Chevy trucks, SUVs, and sedans use various sizes of wheel nuts. However, the most common thread size the Chevy cars use is M14x1 and the Chevy wheel nuts are made of steel.
Will a 6-lug Chevy fit a 6-lug Toyota?
Though Chevy and Toyota use the same bolt partner, their hub bore size is different. While 6 lug Chevy has a 78mm hub bore, 6 lug Toyota has a 106mm hub bore. So six lug Chevy won’t fit six lugs Toyota or other trucks.
Final Words
6 lug bolt patterns are used widely in various trucks, passenger cars, and SUVs. Since all Chevy 6-lug bolt patterns are the same, you can easily find your required lug bolt pattern for quicker wheel replacement.
However, the car’s safety and the wheel’s stability greatly depend on the bolt pattern. So measure the bolt pattern physically if required to ensure that the rim you are using accurately fits with your vehicle. Otherwise, the car’s wheel can vibrate and make it difficult to control the vehicle.
