is this a ram 9 1/4 or dana 60?

how reliable are those rear ends? thats for sale right now with a suregrip 175.00

I've had two in Ram 1500's. One behind a Mag 318 5spd & one behind a Mag 360 auto. Never had a issue, but didn't put many miles on either. There has been some bad stories floating around over the years though. I think it would be better then a 7.25 if that was your only option, but in a performance application, you'd probably be better off looking elsewhere. jmo.
