Anyone done 3.73's in a A10

[Black Stang]

I have a 2019 A10 3.15 car thinking of going 3.73. I will driving the car on sunny days and occasional trips to the local drag strip. I will also be taking some road trips a from time to time but thinking I will be OK with the 10 gears. I traded a PP1 car with 3.55's that got 24-28 MPG on the HWY with the cruse set at 70-75. As for as other mods, I will be installing an H pipe to go with the active exhaust,a stop the hop kit from steeda and a ford performance power pack 2 if they ever come out with one.Just wondering if those that went with 3.73's in an A10 are happy with the swap. Plus if it was raced before and after how did the swap effect 60 ft. and 1/4 mile times.

If you plan on boosting your car, don't do it. If you plan on staying NA, the 3.55s or 3.73s will probably be perfect for you. This is all coming from what I know about the 6r80. The 10r80 might prefer a different diff gearset but from what I've seen, the more power you make, the longer you generally want your gears to be. If you won't ever make huge power, shorter gears will only improve your car's pick up.

Agreed, 3.55s would be fine even for an NA setup and give you room if you ever decided to go boost down the line as well.

would like to do a complete pumpkin swap to 3.73's upgrading short shafts at the same time...then i would always have my 3.15 pumpkin if I went boosted down the road.

No of these replies has answered your questions .. I went from 3.55 to 3.73 nothing really changed as far as drivability ,& slightly reduced sixty foot same 1/4 ET ..My opinion the swap is not worth the money spent unless you do your own mechanic work .
