Just curious...I have an 04 GT manual and do drive on the hwy (not alot) but was wondering what kinda increase in rpm's i would see, say cruisin at 75 with the 3.55 and 3.73...stock 3.27 i'm at 2k....i heard 300 rpm increase per step up so that would be about 2600rpms at 75 with 3.73's..sound right??? I do want more aggressive gears, don't want to beat my stang into the ground, but a 600 increase isn't that bad huh? hell my old BMW was at atleast 3k with stock gears at 75...i drive about 30 miles on the hwy about 3 times a week and drive about 360 mi (round trip) to see fam and friends about once a month...I'm leaning towards 3.73's...thoughts??

 

go 3.73, unless you are looking at serious power adders, turbos, massive boost superchargers then go 3.55, the 3.73's are fine on the highway.

 

id go with the 3.73, with 3.55 youd run 2600rpm and with 3.73 youd run 2730rpm. not to bad of an increase

 

ya i got 3.73's ...i likem alot

 

If your too scared to go with 4.10's at least get 3.73's dude

 

I would personally go with the 3.90's Not as bad in RPM's as 4.10's on the highway but more push than the 3.73's.

 

way to be different! LOL

 

Not to different. A lot of people purchase 3.90's instead of the 4.10's.

 

I could not tell much difference from stock to 3:73, expected a huge difference was dissapointed, go 3.90 or 4.10.

 

JD, when are you getting your gears, what are you going with?
