Winter just arrived here in Ohio, so its time to get busy on the cars for next year!

First Im gonna put 3.23's in my Trans Am. Has 2.73 10 bolt stock, so I need part #RMG-4900031 from Summit, right?

Now what do I need to correct the speedometer? Its the electronicaly controlled version.

 

SGI-5 from Dakota Digital fix the speedometer.

I am not sure about the part though. I put 3.73 in mine so it is a little different.

 

And thats around $80? Do I need to buy anything else with it?

 

I was looking to do the swap but 2.73s are 2 carrier series and 3.23s and 3 carrier series so you need to change that as well. I couldn't tell you what that means, but that's what I've been told many times.

 

That part number I listed is specificaly for the 3.08 and numericaly lower carriers.

 

If you are replacing the axles you can upgrade to a series 3 carrier. If you are keeping the stock axles then you need to get a carrier to matcu.

When I did mine I went ahead and dove into new moser axles for $240.00.
