4.10 gears for 2006 Roush
Well I got some bad news today. I had a noise in the rear end and it seems I need a rebuild. So now is the time to change gears I think. My question is do I get 4.10's? I drive a lot of highway miles and reach cruising speeds of 90 mph. Is the 410 a good gear for me? Or because of my high speed on the highway is a 3.73 better? I still want good pull out of the hole.

If you plan to be driving 90 frequently, then 4.10s might be a bit much, maybe 3.73s would be better. I'd suggest 4.10s for people doing less highway miles or at speeds more like 70, but I think your revs might be a bit high cruising at 90.

As of late I have been doing a lot of highway miles myself. I have 3.55's, and since yours is a 2006 I believe it still had the 3.55's standard too. It is a great gear imho, and the best all-rounder. They are still ok with the ffrp cams, and they provide decent pull.
With 4.10's I would run a sticky tire. 3.55's on a stock car still chirps into 2nd and 3rd and will spin off the line like the best of em on the stock pirrelli's. I posted this clip not too long ago in the video section, but in case you didn't see it (and to save you some browsing time) here it is:
That time in the video is about a second slow from what a stock mustang should do. But with spinning off the line, traction control on (that worked like it should... aka pretty much not at all) a slight incline and 7 years of fun this is to be expected. I might revisit that spot in the future to try and get a better run in, but it still won't be perfect due to the slight incline.
The thing I love about the 3.55's? 3rd gets you to a 100 near redline, and it still pulls nicely in 4th. 4th nearly hits 140 indicated, but is no where near as fun as 0-100. 5th is pretty much overdrive, no real pull anymore. It still gets to the 145 limiter though.

4.10's are awesome. And if you already have 3.55, 3.73 won't big a big enough jump for you to feel difference. 4.10's can annoy me sometimes when i'm driving on the highway because I have a loud exhaust and I cruise at high speeds too. But at the end of the day I'm glad a changed from 3.55 to 4.10
