I am ready to pull the trigger on a GT. I found one that has everything I want and nothing I don't with the exception of 3.73s. The salesman and the dealer have agreed to install 3.73s in the car they have on hand versus me ordering one.

They quoted a very competitive price by the way.

What are the thoughts from the group? Has anyone had this done?

 

does it have the 3.31 or 3.55? if 3.55 it might be worth just leaving it be

 

No way ... you risk invalidating the warranty on your entire rear axle and driveshaft if you let the dealer swap gears. You can order or locate another car with the exact options you want.

I could possibly see doing it if it were a 2010 and the dealer was swapping gears as an incentive to sell the old inventory ... but I would still want a written warranty from the dealership for the entire rear driveline above and beyond the factory warranty.

 

Your warranty will still be intact if the dealer does it.

I say go for it I love my 3.73's

 

I thought this was the case as well. I would check on that. As long as your dealer knows what they are doing and warranty their work I say go for it!

 

It won't affect the warranty on the rest of the car at all, and the dealer should warranty any work they do so there is no warranty issue. Just make sure it is all documented.

 

My dealer was not interested at all in quoting me any price for that. Maybe it's b/c I ordered/bought my car on a late Saturday afternoon.

So what price did they quote you?!?

 

They quoted $400 so it would be about the same as if I had ordered the car with the 3.73s.

 

$400 parts and labor ... Wow! that's quite a deal!

 

Correction, it was $695 parts and labor on the rear end install.

 

You shouldn't let your dealer install 3.73s....


...you should let him install 4.10s

 

lol... nice

If it was me i would probably do it. I am hoping to install 3.73s in the near future.

 

No use of having 4.10s for street use only. First gear will totally be useless. I know, i have 3.73s.

 

4.10s are too much gear for me. Once upon a time I had a 72 ventura with a 4.56 gear. That car was useless for anything other than 1/4 mile runs but it did that really well. I want the 3.73s for the performance and to ensure the car is always eager and ready when I want to get into it.

I am still not sure about letting the dealer do the swap. I hear it is a very straightforward job and that there should be no way to tell that it was done at the dealer vs the factory. I still have my doubts though.

 

I don't know if I would call a gear swap a very straightforward job, takes a variety of specialized tools and skill set to do a proper job.

A Ford dealer service shop should have a skilled tech and the proper tools though.

But, yes, once done you would never know that it wasn't a factory job except that the breakdown of the VIN # would tell a dealer that the gears weren't factory installed, but nobody else would ever be able to tell.

 

Ring & pinion swap is a routine job for most any dealer. Most are plenty talented enough to do it right the first time. I've had our local Ford dealer do several gear swaps for me over the years, including the 4.30's in my '03 Mach 1 and the 4.10's in my '07 GT.
