Well got word from the dealer shes been ordered!!! Just disapointed the 4:10 axle went a way instead its a 3.73 :(

 

They're not offering the 4.10 at all for '08?

If that's true...wow! It must be to get the average mileage higher than it is.

 

What kind of delivery time are they giving you?

I am looking to place my order as soon as the stealerships in the area will let me. Really want the Unlimited Rubi loaded up. Really don't want to have to wait as long as some ofthese poor people here have for theirs.

 

they were guessing september.

and ya it looks like the 4:10 is gone except on rubi's

I hope I can install the gear kits on the 3.73 diff.

 

My dealer called me yesterday and said he placed the order, and September was his guess also. A prudy jeep green '08 Ruby!

 

Did the dealers give you prices, the dealers I was talking to here said they can put it in, but it doesn't give them any prices yet.

 

we had agreeded on invoice.

 

Wonder what type of mileage diff that can be?

 

You may have just ordered a 2009 without knowing it (how long will it take to be built) and by then the 4:10 might be back.

 

I'm not sure on the JK, but it does make some sort of a difference because when you're driving 65mph when you have a 3.73 rear end, you're engine is running at lower rpm's than if you have a 4.10 rear end.

On my dually, I have a 4.30 rear end vs my last truck I had a 3.73. My mileage went down almost 2 mpg when I went with the 4.30!
