I am swapping the gears on my 2010 auto sport. I found a good local shop but they said I need a new carrier for my front d30. Is that accurate? It is the only shop that I talked to that mentioned a new carrier. I have the master overhaul kits.

I am switching from 3.73 to 5.13.

Yes ..........

Ok, thank you. I wonder why they are the only shop that mentioned the new carrier.

I thought you only needed a new carrier if you had 3.21s and the carrier on the 3.73s and above were the same.

DanieltheManual

Ill correct me.d30 newcarrier not needed..... 373 and up. So you are gooood.

Anyone have a definitive answer?

3:73 and up you can use the stock carrier I am running my 5:13 on my 2010 with the factory carrier. If they are telling you they won't fit I would find another shop cause they either don't know what they are doing or trying to sell you parts you don't need.

Agreed. FIND A NEW SHOP. With 3.73s you will not need a new carrier.

I had no problems when I did mine...

Thanks for the information. I called Northridge as well to confirm and they said the carrier for the 3.73 will work just fine. I'm going to call the shop back and see what they say.
