I'm considering on ordering some 4:10's for my 03 GT very soon. This spring I am most likely going to put a 75 shot of nitrous in her. Would 4:10's be to steep for this setup? I've heard 4:10's with a s/c doesn't work very well. Is it the same with nitrous?? Thanks Kyle

For your 96-98 GT Manuals, 3.73 gears are nearly equal to 4.10's in a Tremec 3650 transmission found in 01-04 GT's. For 96-98 GT's 3.73's are fine, but going with 4.10's is still a better idea, far better idea actually.

With a blower, it depends on your application. Are you going to just run around on the street? Have you done any suspension modifications to make use of new gears? 3.73's seem to be the gear of choice for a supercharger, as most people won't be running around on BFG Drag Radials or Nitto's all the time on the street. Ideally, you want a 4.10 gear in there, but you have to be willing to run ATLEAST some LCA's and a set of radials.

For NA 01-04 GT's, even 99-00 GT's with the weak tranny, 4.10/4.30 are the IDEAL gear. When people start talking about "running out of gear" or "redlining before the traps", these things are easily offset with the help of a little traction and TALLER tire.

I had 4.30's in my 02 GT, I got over 20mpg in town with several runs through the gears. Originally I had 4.10's and decided I didn't have enough gear and went with 4.30's. ..That's how bad 2v 4.6's NEED AS MUCH GEAR as you are willing to give them. I wasn't shifting every other second, it wasn't a pain in the *** to drive, infact compared to my buddies 04 GT with 3.27's in it, my car was FAR easier to drive and it didn't do any of the bogging my buddies car did.

Does anyone have a gear suggestion for a 2003 GT with a T56 Tranny, n/a?

rbstang

I thought 03's had the tremec3650

It does stock, but I'm going to put a T56 in eventually. Any suggestions on the gear ratio?

i have had my 3.73 for about 500 or 600 miles and when do u want to change my diff fluid ?? how do i know if they are broken in right or have chips in them

They do have a Tremec3650 stock, maybe he swapped in a T56 though? Even with a T56 you still want 4.10's.

What's a good price to have gears installed? I've two places out here quote me $500 and $600. I also found some 4.10's for $150, is that a good price?

Fallstar01

No, that's a terrible price. You should reasonably be able to get them installed for half of that.

Im getting my 410s installed on Friday guy quoted me $350-400 for install... i only chose them cuz they come highly recommended. otherwise i woulda called other shops. So ya $500-600 there trying to rip you off dude.
