Introduction

In this episode of “I Never Knew,” we’ll be discussing bolt patterns and how they apply to the 1969 Chevrolet Impala. Bolt patterns can be confusing, but we’re here to help you understand them better. We’ll cover the basics of bolt patterns, how to measure them, and common misconceptions. By the end of this article, you’ll have a clear understanding of bolt patterns and be able to confidently choose the right wheels for your Chevy Impala.

Key Points

  • Bolt patterns are a crucial aspect of wheel compatibility.
  • Manufacturers often use dual-drilled wheels to fit multiple vehicle models.
  • Bolt patterns can be expressed in inches or millimeters but mean the same thing.
  • Chevy Impala has a 6-lug bolt pattern, specifically 6x5.5 inches.
  • Measuring a bolt pattern involves identifying the distance between opposite corners.
  • Covered center caps are common in most wheels, but some have exposed lug nuts.
  • American Force wheels have exposed lug nuts due to their custom-made forged design.
  • Spike lug nuts are not suitable for dual-drilled wheels as they would leave extra holes visible.

Understanding Bolt Patterns

When shopping for wheels for your 1969 Chevrolet Impala, it’s important to pay attention to the bolt pattern. The bolt pattern refers to the number of bolts and the distance between them on the wheel. For the Impala, the bolt pattern is 6x5.5 inches.

Manufacturers often use dual-drilled wheels to fit multiple vehicle models. This allows them to save costs and eliminates the need for separate molds for each wheel model. In the case of the Impala, the wheel is drilled for both a 5-lug pattern and a 6-lug pattern. This means the same wheel can fit different vehicles like Toyota Tacomas and Ram 1500s.

Measuring the Bolt Pattern

To measure the bolt pattern of your wheel, you need to find the distance between opposite corners. For the Impala’s 6-lug pattern, you would measure the distance from the center of the far right corner to the center of the far across corner. In this case, the measurement would be 5.5 inches. The second part of the bolt pattern specification, 6x5.5, indicates the number of lugs and the distance between them.

Covered Center Caps vs. Exposed Lug Nuts

Most wheels come with covered center caps, which hide the lug nuts. However, some newer wheels, like those from American Force, have exposed lug nuts for a more aggressive look. This is possible because American Force wheels are custom-made and forged, rather than cast, meaning they can accommodate specific bolt patterns and sizes.

It’s important to note that spike lug nuts are not suitable for dual-drilled wheels. They would leave extra holes visible and affect the overall aesthetics of the wheel. Therefore, it’s best to stick with regular lug nuts for dual-drilled wheels.

Conclusion

Understanding bolt patterns is essential when upgrading or replacing wheels for your 1969 Chevrolet Impala. By knowing the correct bolt pattern, you can ensure a perfect fit and avoid compatibility issues.
