8.25 to 8-3/4 or nah!??

I wouldn't spend the time on an 8 3/4 unless your going to the strip every weekend. The 8 1/4 is tough. Also lighter than the 8 3/4. Just swap out the carrier for a suregrip and put in some street friendly gears. Way cheaper and it will suit your needs I'm sure. I beat the hell out of my rear end, never had a problem. I'm sure some other guys here will tell you the same.
