A little pricey for the power output, but combined with the added strength, reliability and less rotational mass I think it's worth it.
I would have to agree with Hogasswild here.

i dont mean to contradict myself i just realized i worded my initial question poorly. And yes ive only seen the drive shafts for 500-700 and thats seems like an aweful lot but in the long run i guess it would be worth it if i continue to mod the car. the poeple i have heard of using 4:10s on their autos do almost no highway driving so i would assume thats why they prefer them since their RPM's are never high. But thank you both, i think im going to stick with 3.73 when i finally upgrade

Yes, I have the 3.73 in my Stang and I love it.......4.10 are more for the strip and not for a daily driver. If you went with the 4.10 your MPG will take a huge hit not to mention high RPM's when on the highway! But it would be fast on the strip.

No problem man. The reason I'm being harsh on you is because I don't want to see you mod your car without knowing what those mods do. Mods can void your warranty, destroy your differential, throw error codes, and cause engine problems if you don't know what your doing.

The drive shaft subject is one that is often debated.
Some love it and say it helps, some hate it and say it causes problems.
I'd say it can do both. I've seen and heard it enough in different situations.

I'm always on the YES side of upgrading the gear ratio from stock as long as you
don't have a really aggressive ratio from the start.

That's not bad. As long as I can get 27 mpg on the highway I'll make the switch.
