What is the Chevelle bolt pattern?
The Chevelle’s standard lug pattern is 5 on 4.75 inches (5x4.75"). This bolt circle is used by most GM A-body Chevelles from the mid-1960s through the early 1970s and remains the baseline for wheel compatibility today.
What is the Chevelle bolt pattern?
The Chevelle family, including the Chevelle sedan, Malibu, and El Camino built on GM's A-body platform, commonly uses a 5-lug pattern on a 4.75-inch bolt circle. In wheel terminology, this is written as 5x4.75" (127 mm). This pattern is widely shared with other GM cars of the era, which helps with parts availability and aftermarket wheel options.
Generations and coverage
While the 5x4.75" pattern is the standard for the vast majority of Chevelle A-body cars from 1964–1972 (and their GM siblings from that era), individual factory configurations or aftermarket substitutions can vary. Always verify for your exact year and model, and measure the bolt circle on your existing wheels if you’re unsure.
Before the list below, here’s a quick reference to what you’re typically dealing with:
- Standard: 5 on 4.75 inches (5x4.75", 127 mm) bolt pattern for most GM A-body Chevelles and related models from the 1960s–early 1970s.
- Compatibility: Many aftermarket wheels are offered in 5x4.75"; wheels in other patterns exist but may require adapters, which can affect fit and safety.
- Important considerations: Check center bore size and brake clearance in addition to the bolt pattern to ensure proper fit and hub alignment.
In short, the Chevelle’s standard wheel pattern is 5x4.75" and remains the baseline reference for wheel compatibility on classic GM A-bodies. Always confirm your exact year and trim before ordering wheels or adapters.
How to verify your car's bolt pattern
To verify the bolt pattern for your Chevelle, you can measure or consult documentation. Here are practical steps you can take:
- Count the number of lug holes on the hub (most Chevelles have five).
- Measure the distance across the lug centers from one hole to the diagonally opposite hole to determine the bolt circle diameter. For a five-lug pattern, this should come out to 4.75 inches on a typical Chevelle.
- Check the center bore size of the wheel and the hub bore on the car to determine if a hub-centric ring is needed for proper centering.
- Consult the vehicle’s manual or a trusted parts catalog for your exact year and trim to confirm the bolt pattern, or use a lug-pattern gauge for accuracy.
With the bolt pattern confirmed, you can confidently select wheels that fit without spacers or adapters, or decide if adapters are necessary (and what clearance implications they may have).
Summary
For most Chevelle models, the bolt pattern is 5 on 4.75 inches (5x4.75"). This is the standard GM A-body pattern from the mid-1960s to the early 1970s and remains the reference point for wheel compatibility today. Always verify your exact year and trim, measure the bolt circle if in doubt, and consult a wheel professional if you’re unsure about fitment or potential need for adapters.
