Iv heard 4.10's are nast on the rear. Few good passes and its all over with. Is this true. I was thinking about gears but dont want to spend 2K on a new rear as well. And is there that much of a differance between 4.10's and 4.11's. I really want gears but dont wanna shell out $2,000 for a new moser 12 bolt.

Ive had 4.11s on mine for about 2 years now . I have no mods done to the rear or axles. i run mine pretty hard on the street and strip. But i not really that fast 12.2s on average. Only problem is my speedometer was off by about 8mph but is a easy fix.

As long as your spinning tires you won't break anything.
It's only when you put sticky tires on that you need to worry.

If you get 4.10s installed properly, and maintain the rear end, i change my rear lube now with every oil change every 3-5k mi depending on how hard i am on the car, you shouldn't have any problems, i would invest in a TA rear end cover, because the caps that hold the diff in can start to stretch because of the increased load being put on the rearend when you are hard on it.
