Mods please give this a little exposure before relocating it :) I know this has been asked before, but I want to get some feedback before next week on what our 4.0 group says. V8 owners, I appreciate your feedback but I am specifically looking for practical application experience, results will vary on your GT.
I was going to get 4.10's but I keep hearing different opinions from different people.
I drive my stang daily to work, I do alot of highway driving around Houston, avg. 70-80 mph. My work commute is usually 40-60 mph. My stang is an auto.
Which gear should I get and why? How much of a gas mileage difference is it between 3.73 and 4.10's? How much more engine wear will I get with 4.10's (and is it even an issue if I do regular maintainence?) How much performance difference between 4.10's and 3.73?
I'm with you Oddesey, I also drive 40+ miles each way to work (Pasadena - Eldridge/290). Mornings is non-stop 70 - 80, afternoons it is just the opposite, in fact I find it better to shoot thru town Texas - Harrisburg, etc. I've read on this site that 3.73's for a 5-speed and 4.10's for auto, I am planning on 3.73's in the future. One question, is thge T-Loc necessary if you don't race?
Chuck

From what I have read and seen 4.10's for Auto and 3.73's for Manual Trany. Check out the post I put on the T-LOC post and give that guy a shout out I think he has some good addvice on the matter at Chips v6 Specialties you can not beat or find a better price on a T-LOC but I have not got one from him yet. web page is http://store.chipsv6specialties.com/c75tr719.html I would think he would welcome any questions you may have. I do not Race or Drag my car so I intend to keep the same stock gears for gas mpg.

i ordered 3.73's for my auto which should be arriving today. my stang is not my daily driver, yet i still didnt feel like jumping too high with 4.10's. i have no race intentions except for my car being a weekend fun machine and road trip traveler. i've read MANY posts and reviews on both gears and just felt that 3.73's would suit my preferences better. As for the t-lok, i will be ordering that today or tommorrow. after spending the weekend in vegas, where it had rained some which made the roads slick, i am anxious for the lsd. i was sitting at a light and when the green light lit i accelerated mildly and my "ONE" tire slipped and i was just still sitting there at a green light with a spinning tire trying to go. i had to let off the gas and start over even more mildly to catch traction. this felt kinda lame which made me realize how important an lsd is especially for modded stangs. if you are going to start moddding your stang, add a lsd to your list!!!
I have no experienece with 4.10s, but my experience with the 3.73s has been great. The car is more responsive all around (launch and highway). I do have trouble with traction off the line with the 3.73s.. that might change in the summmer.. but I would expect more traction issues with the 4.10s.

you also have an lsd, correct? i guess quick launches could be a traction issue but i guess i will have to adjust to it.

theres the problem, 4.10s are completely sutable for a DD car with an overdrive, get the 4.10s its worth the extra 1 mpg on the highway, city milage will actually probably go up slightly if you can keep ur foot out of it

^^^ haha....ur like the 4.10 advocate. ur points are understood but then again, why doesnt all NA stang owners go with the demolet or c&l intake? those two put down the best numbers yet we realize that its all about personal preference and intentions. not all want to mess with the ecu just like not all "need" the high reving 4.10's. again, i'm sure the 4.10's are hella fun but i'm just looking for nice/non excessive jump in acceleration. i'm sure others who are considering 3.73's feel similar (unless they are going f/i).
I also went with 3.73 just in case I was lucky enough in the future to get an xcharger. i drive between 70-85 mph on the highway on long trips and was worried about gas milage with the 4.10s. I don't recall what rpms i'm at going to speed.. but it's a noticeable difference from stock... but not in a bad way.. I can actually pass using 5th gear now. With regard to traction.. I do have a t-lok installed.. but that would only help.. My car is pretty peppy off the line.. and I have to consciously keep myself from jumping. Not sure if that's just me or the gears and tune .. either way.. I love the way the car drives now.

When deciding on gears, you must also consider rear tire diameter, as that affects your final gear ratio. I have 4.10:1 gears in my 5-spd coupe, but I prefer the 28" dia drag radials from M&H, which measure 275/50R17. The taller tire drops/raises my gearing to 3.95:1, versus the stock 17" Pirellis. Conversely, a 26" dia DR like the Mickey Thompson ET Streets will change my final gearing to 4.25:1.
So you need to consider the tires you are planning to run after the gears are installed.

very good overlooked point. personally, i'm sticking with the 17" pirelli's.
well im not exactly sure which way to go either yet, been debating it for a few months, either 3.73 or 4.10 with tlok (slipping from the redlights in the rain sucks)
can you all give me prices on how much it costed to installed and how much the parts were? I just want an estimate, i plan on having a frrp ford dealer do it because it'll keep my warranty from being voided which is good.

i found a local shop that will do the install for $350. i'm supplying the 3.73 gears and t-lok. the shop specializes in drivelines and they even manufacture their own mustang driveshafts so they will supply all remaining parts needed, bearings, washers, etc. as for ford doing it, i would expect a few hundred bucks more.

Where are you located? I need one in the San Fernando Valley/LA area (willing to drive far.)
Also, my plan: Get a CAI, tune, and gears + tlok all done at ONCE, then, when I roll out of the shop, unleash the beast.
I won't know the difference between stock and either just gears or just CAI. I'll get the full brunt.
-- Will that be too dangerous as I wouldn't know how to drive my own car?

I have been doing alot of thinking on what you said Bill and I think that is what swayed my final decision to go with 3.73's.. I have 26" dia. on the back of my car so with 3.73's I should be running around 3.90ish right? Do you have the formula for figuring that out?

just got an install appointment for 3.73's & t-lok on monday. really looking forward to it. i originally had some used 3.73's but the shop i'm getting it done at already has brand new ford 3.73's for $200, which he highly recommends for a newer street car since used gears already have an existing wear pattern from the previous vehicle. i guess its better piece of mind and at least i'm getting ford oem gears. i'll keep u all posted.
Noober, you won't unleash anything for 500 miles. :) Gotta break the gears in, so you dont screw it up. I paid $785 parts, labor, tax for my 3.73's and t-lok.

3.73 or 4.10's - 
.. either way.. I love the way the car drives now.
