yep, finally got the gears installed and got the car back thursday of last week. i freakin' luv'em! ya'll were right, don't fear the gear. it livend the car up a lot with very few adverse effects. i gotta pick up an sct excal.2 or livewire tho, damn speedo is off a bit, bout 5mph. other then that, i'm kickin' a shade over 2k rpms @70mph in 5th, so not too bad! as for gas mileage, from what i can tell not too bad either. this mod was def. worth the $800 it cost! the t-lok is a reall fun mod also. yup..just figured i'd let ya'll kno.

 

Glad we could help out, now you got the extra traction and gearing for some power adder

 

does it seem...ALOT faster? Like almost GT fast?

 

thats what i'm thinkin'. i want to try and build the motor a bit before a poweradder. so when i do put a turbo/sc on it, i can use it to full potential.
speaking of which...anyone know of a site that offers parts to build up the 3.8?

 

eh, i wouldn't go that far. i'd like to go up against a stock GT to see where it stands tho. i mainly feel it after i get goin', from around 30 on up. it does have some gittupngo from a stop tho.

 

awesome! hopefully I'll be doing that mod next summer.

 

def. worth the money

 

sound sweet what brand did you buy and where did u find a 7.5 tlock?

 

motive 3.73's and a motive bearing and gasket kit (whole thing, not install kit), both from AM. and the t-lok i found at jegs.com for 240? sumthin' like that. v6mustangstuff.com has it for 199 tho, but ive never ordered from them, and i trust jegs.

 

for any one who has a s197 with a v6 and a 7.5 rear. check out www.newtakeoff.com they full ready done take out rears with less then 10 miles on them with 3:31 LS up to 4:10LS axle to axle bolt in's.

i did a 8.8 LS w 4:10's under mine to handle the stage 3 procharged 4.0L in mine for less then a G note. good thought when pushing the envolpe in power to more then small 7.5 can handle with out breaking like i've done.

 

i just checked that site captchas, they do have some great prices. where the hell were ya about 2 weeks ago damnit! lol

 

Will those rear end assemblies for the 05-07 fit on an 04? If they do, I might get one with the 3.73 gears on it. I think it will save me a bit of money rather than getting a Detroit Truetrac and 3.73s for my 7.5

 

i think the truetrac is better then the frpp t-lok. but the 8.8 is def. better then the 7.5, so i guess it's a give and take thing on this one decision.

 

no the 05+ rear end is setup for a 3 link rear end and we use the tried and true 4 link setup.

 

Ah crap. Oh well. Can't blame me for trying I guess. 7.5 rear end, 3.73s and a Detroit Truetrac it is then!

 

speaking of the 7.5 rear end, anyone know what the max tq rating is? or their opinion of how much they would put on it?

 

I dont know any exact numbers, but I believe the more you bolster it, the more it can hold. Obviously. I myself will be using a Detroit Truetrac, gears, and anything else I can find that might make the 7.5 stronger. That should hold a good amount of torque. Unless of course, I can find an 8.8 for cheap.
