Question 2013 5.0 Gears?

I've got a 2013 5.0. I cant seem to decide on which gears to go with, Im caught between 3.73's or 4.10's... I read that there really isn't a big difference in gas milage between the two if you have a 6 speed manual, which is what I have. If that's true, then I'll definitely go with the 4.10's, but if it completely kills gas milage, then I'll most likely go with 3.73's.

I do some freeway driving, but I'll be moving into the city within the next few months, so I won't be making the long freeway drives anymore.

Let me know what you guys think and what your experiences with the two are. I'd like to order the gears on Monday if I can figure out which ones to get by then.

Thanks,
Cameron.

ok, there are other threads with this answer, but you have to throw some things out there first.

What gears are you currently running?

Are you planning on doing FI at some point?

Are you installing the gears yourself?

4.10 are too steep for FI so unless you want to change them out later 3.73 are your best bet. I went from 3.31 to 3.73 and it is a huge difference.

I only asked about having a shop do it as a lot of shops seem to run gear specials where you buy everything from them and they give you a discounted deal. I got my gears done for 550 which included everything. 3.73 frpp gears, royal purple fluids, rebuild kit, etc.

I think the dealer can reset the speedo calibration too.

I'd go with the 3.73's. I always had the opinion that that is the perfect gear for a DD.

The factory stock gears in the 2013 GT are either 3:15, 3:55 or 3:73. Only factory 3:31 gears are offered on the V6 model. So which factory gear ratio did you get when you purchased your 5.0

Wrong. The standard 6mt gear for GT is 3:31 with options for 3:55 or 3.73.

Well I know the auto has 3:15 not 3:31. So your saying the manual has 3:31. Learn something new every day. Very interesting. I wonder why Ford would use a different gear ratio for the automatic compared to the manual. Since the OP has manual, he could have either 3:31, 3:55 or 3:73 factory gears.

You have 3:31 unless ur sticker shows a different gear option.

Where your gears are located look for a plate should be stamped what gears are in your rear diff.

This is from another thread on here.

You can check either the sticker on your differential or the door jam sticker on the driver's side:

The Ford axle ratio codes are:

BB - 3.73 ratio
CC - 2.73 ratio
DD - 3.55 ratio
GG - 3.31 ratio
YY - 3.15 ratio

Because the gears in the 6R80 are different than the MT82.

I have 410 gears on mine. I drove it from Milwaukee to Myrtle Beach last summer for Mustang week- got 22 mpg avg on the trip. Didn't think that was too bad. Turning about 2200 rpm at 72 in 6th gear.
