I’ve been restoring my 1969 Camaro for a while now, and I’m at the point where I need to make some decisions about the rear end.

Current Setup

Right now, the car has the stock rear end, but I’m considering upgrades. I know that the original 10-bolt can handle a decent amount of power, but I’m thinking about potential performance modifications since I’m aiming for a little more horsepower.

What Should I Consider?

  • Upgrade Options: What are the best rear end options for someone looking to boost performance? I’ve heard about 12-bolts being a popular choice for muscle cars, but I want to hear personal experiences.
  • Installation Tips: If you’ve upgraded your rear end, what installation tips can you share to make the process smoother?
  • Compatibility: I’m also wondering about compatibility with the existing components. Will most aftermarket rear ends fit with my current driveshaft?
  • Specifications: Are there specific specifications I should look for when purchasing a new rear end?

Seeking Guidance

I would appreciate any advice or personal stories you might have regarding your experiences with rear ends on a Camaro. Is it worth the investment? How did it affect your driving experience? Any help on sourcing parts or brands would also be greatly appreciated. Thanks in advance for your insights!

Looking forward to your responses!

Hey! If you’re considering rear end upgrades, starting with a higher gear ratio like 3.73 or 4.10 can really improve acceleration. It all depends on your driving style, though!

I totally agree! I have a 4.10 in mine and it made a huge difference. Just be careful if you drive on the highway a lot.

Thanks for the suggestions! What about differential types? I’ve heard positive traction is a good way to go.

5

Absolutely! Upgrading to a limited-slip or locker differential can enhance grip, especially during hard cornering. A great upgrade for performance!

Don’t forget about the benefits of a lightweight aluminum rear end. It can reduce the car’s overall weight and improve handling!

7

That’s a great point! But make sure to consider the costs; aluminum can be pricey compared to traditional steel.

What are your horsepower goals? Different setups can work better depending on whether you want a street friendly ride or a full-on drag racer.

I’m aiming for a good balance between street performance and occasional track days. What do you guys think about adjustable control arms?

They are fantastic! They really help tune your suspension for better traction and handling. Definitely worth considering.

Upgrading the rear end can be both fun and challenging. Anyone ever considered going with a Ford 9-inch rear? Tons of aftermarket support!

12

I’ve thought about it! But they can be a bit bulky. Anyone had issues with fitment?

13

No issues for me, but remember, with great power comes great responsibility! Make sure your brakes correspond to whatever upgrade you choose.

That’s true! You don’t want to upgrade the rear end only to have brakes that can’t keep up. Safety first!

I’m having similar issues with my rear end. I suspect it might be leaking oil—has anyone experienced this with a 1969 Camaro?

Leaks can be a common problem. Check your rear axle seals; they’re likely the issue. Also, a good oil change can help address minor leaks!

If you’re hearing any noise, it could be time for new bearings. Those tend to wear out over the years. Just tackled this on my '69, and it made a world of difference!

Great point! Old gears can also contribute to handling issues if they are out of alignment.

I agree with xhill. Misalignment can turn your ride into a nightmare! Have you checked the suspension components, too? They can play a huge role in handling.
