When it comes to vehicle restoration, modification, or performance upgrades, knowing the rear end width of your Chevy is crucial. Whether you’re working on a classic Camaro or a newer Silverado, these measurements can make or break your build.

Why Rear End Width Matters

The width of the rear end impacts not only the fitment of your wheels but also the overall stance and handling of your vehicle. If you’re swapping in a new rear end from a different model, getting the dimensions right is essential for both aesthetics and performance.

General Widths for Common Models

Here’s a quick breakdown of the rear end widths for some popular Chevrolet models:

  • Chevrolet Camaro (1967-2002): Generally ranges from 58.5" to 60.5" depending on the year and model modifications.
  • Chevrolet Corvette: The widths tend to be around 60" for C3 models and can vary slightly for C4 and beyond.
  • Chevrolet Silverado (1999-2019): The rear end width is approximately 67.5" which can differ based on whether it’s a 1500 or a heavier model.
  • Chevrolet Tahoe: Similar to the Silverado, expect around 67.5".
  • Chevrolet Malibu: Typically about 59" but varies based on the year.

Sourcing Detailed Charts

While I’ve shared some general figures here, I highly recommend checking out specialized forums or resources for detailed charts. You can often find them on dedicated Chevy restoration websites, user-created wikis, or even in the manuals of specialty shops.

I found a GM rear end width chart that covers models from the '50s to the '90s! It’s super helpful for those of us working on classic cars. The widths have really evolved over the decades.

Sure! I found it on a classic car forum. They’ve got a section dedicated to GM and Chevrolet rear ends. It’s definitely worth checking out!

I didn’t know that. I’ve been looking for exact measurements for my '69 Camaro’s rear end. Any specifics on that model?

The '69 Camaro typically has a rear end width of around 60 inches. Make sure to double-check because variations can exist depending on the setup!

Wow, that’s a really helpful piece of info, ingramchristopher! It’s amazing how much these specs can vary over time and between models.

That’s great, but what about more modern Chevys? I need to know if the widths have changed significantly in recent years.

Absolutely, roy03! Modern Chevys like the SS models have widths that can range from 61-63 inches. If you’re planning a swap, you might want to keep that in mind.

The widest rear end I’ve seen is from the '15+ GMC Denali, which can be around 67 inches. Adding that to a smaller frame would definitely be a challenge!

If you’re going that route, make sure you have all the right adapters or you’re just asking for trouble! It’s all about having the correct fit.

I don’t have a full chart, but remember that rear end width can significantly affect your car’s stance and handling. It’s key to know your wheel offset as well!

13

Exactly! Tire size is another crucial factor. Wider tires require a more specific width to avoid rubbing against the fenders.

14

Agreed! The performance implications can’t be overlooked either. A mismatched rear end can throw off your gearing ratios and affect overall speed.

15

Exactly! It’s also important to consider how the rear end interacts with your suspension setup.

Great points! Also, if you’re swapping in a non-factory rear end, check if the mounting points on the frame match up. You don’t want any surprises.

Very true! I made that mistake once and had to do extra work to get it right. A good rule of thumb is to stay close to stock dimensions.

That’s valuable info! And don’t forget, the type of rear end (like 10-bolt vs. 12-bolt) can also affect your choice based on performance needs.
