If you are worried about mileage you shouldn't be driving a mustang. Get the gears and don't look back. 80-85 Mph at 3K is fine. The only thing they are going to do is put a smile on your face.

A full day's labor is a complete rip off by the way. I paid about 600 for mine: gears, rip off royal purple gear oil, bearing set and labor. I though I overpaid a little but they did a great job installing.

I am not "worried about" GAS mileage, but I am concerned about reliability and durability of the rear end and the whole drive train.
I am a prospective buyer of an 05 manual 4.6 GT with 45K mi - this car, especially with 4.10 added soon after purchase, WILL have decent longevity in the drive train, yes?
The 4.10 means this, if I drive say an additional 80,000 miles on it, that's 125K on the engine. The 4.10 means the engine has maybe 15% - 20% more rpm's on it than stock rear.

I assume this engine is good for it... other things will need replacement BEFORE the engine or the rear end, right??

I'm kinda curios on this one, and then on the other spectrum if I say put on A SC and dropped in 3.31 that would mean less revolutions on the driveTran and therefor increasing the life of the part but wearing out the engine quicker (had to edit this), in a way it may be the answer more horsepower and higher gears means lower RPM on the interstate therefor less wear on the engine and oh god my brain just detonated like a SC'ed engine running lean and nw I'm cross eyed, ouch

Drop in a 3.31? AT come w 3.31 , right? Manual, with 3.55 or so.
I don't even own a Mustang.. so consider my words from that perspective !! I just like gears- lower gears for more instant power- quickness like Bruce Lee. In traffic, quickness is my fave mod- not top speed.
I prefer quickness to 1/4 mile though. I prefer a 6 speed to a 4 speed. You can almost instantly be right in the ideal power band/ optimum torque, via the gearing.
No waiting. Waiting, is not racing!

How do you go about finding a good place to install your gears?
