thanks..... i dunno if im gonna need duals? i got the 4.70's so ill see how those do...and i have budbuilts single t-case crossmember, which can be adapted to duals later on if needed... just gotta buy the adapter kit. i plan on wheelin it maybe once a month so i think that just having 4.70's isnt gonna bother me.... unlike with duals u have the option of being able to run 2.28...
