the lock outs are for the snow or if this stupid thing ever actually does see some road time. it will run flanges mostly always. im going to buy a set of drive flanges as well basically just for the hammers cause its knarly down there compared to any of the other trails i usually run. not saying a lockout wont break on fordyce or rubicon, its just your putting the truck through 3x the amount of stress and not just for 2 days. its a week long event so thats where i justify having both.
