Just picked up a '25 GT, manual with 3.55s. Car is great, but its a slouch down low.

Wondering if its possible to have 4.xx's installed at the dealer or a reputable shop. Don't plan on supercharging the car at any point.

If so, any recommendations in the Phoenix, AZ area?


Thanks.

Any Ford Dealer or reputable shop can do a gear swap. In my 2006 GT when I swapped in the Tremec Magnum XL 6 spd. I had 4.10's put in the rear with an Eaton posi and she is great. Go 3.73 or 4.10's would be my recommendation. 4.10's will really wake it up.

That's what I was looking to hear.

Thank you.

I was thinking of swapping to 3.55s from 3.15s, the car is painfully sluggish down low for having 480hp
Horribly sluggish. My first Coyote was a 2013 GT/manual and it felt better. Granted that car, I believe, was a bit lighter. I understand the Coyote likes to rev - just need to get it in its power band a bit quicker.

Agree. Had 4.10's in my former SC Roush Mustang, found them to be too much, pretty much had no 1st gear..dropped to 3.73 and that was much better, would still hit rev limiter, just not as often...........FWIW, car had been tuned to 390 RWHP

Your 2013 had different gear ratios in the MT-82. 1:1 wasn't until 5th
