ok so i went with 3.73 gears through motive which is now a ford racing product i paid 365 for the full set and everything to put them in then 150 to put them in but thats canadian so i prolly dont count lol

 

counting the revs on wheel and drive shaft ain't real accurate just buy a gasket get off your lazy but and count the teeth on the ring & pinion then divide ring by pinion i personally like a 3.73 it performs good and you can stay under 4 grand at highway speeds just depends on what you want stay with the 7.5 till it breaks

 

I replaced my 89 convert 2.73s to 3.55s and it is nice. My 90 GT was switched from 3.08s to 3.73s and it was sweeter!

 

I just got aset of 3.90's installed and was curious if they have to be broken in before i race?

 

Testing...testing.....1....2.....is this thing on

 

Is it true that 05-07 A/T GT'S only have a 331 axle ratio.

 

I have a 2001 mustang gt 5 speed with bassani o/r xpipe, mac CAI, High flow injectors, mac underdrive pulleys, and i think 3.73...I want to get better acceleration like 4.10 but do some highway driving and was wondering would 4.10 work or should i go with 3.90. I dont want to be at 4 to 5 thousand RPM's constantlywhile driving around. Let me know guys cause i want to get them soon.

 

I got an 02 v6 convertible 5 speed and I dont know what gear mine is.
Also i want to upgrade and I would like to have something that gives me more pep, but still is all around good on the gas.

 

I understand completely about ur gear havoc. I have 4.10 gears in my 88 mustang gt but thats 4 drag purposes. It depends on if ur car is manual or automatic. If ur car is automatic u can usually go as high as 355 and still have the sunday drive affect u r lookin 4, but if u have a standard shift u can go lower becuz u have the extra gears. I am thinkin about switchin from 410's to 373's bcuz I want 2 b able 2 come off hard and still roll to the big end. It all depends on what u want and what kind of transmisson u have.

 

i would go either 3 73 or 410 both really good my buddys 95 rips and he has 373 and my other buddy has 410 and rips but not really that sweet ont the highway but also can do 3rd gear burnouts whenever
