It's worth it if you’re going to use it. You’re modifying your truck from factory specs and with that you’re going to have to beef up some parts if you’re going to wheel it hard along with added maintenance. The steering components being the main part that fails quickly after a lift. The steering systems on the market do address the weakness and work well but they do require regular maintenance if you want to get the most life and best performance out of them. Also when you leave the highway and start going over big rocks through sand/mud/water/dirt your going to stress and wear the components a lot more than Sally soccer mom running little Johnny around town. A lot of the guys you’re reading problems about push there trucks hard and that’s causing stuff to wear out quicker.
I don't believe the lift is causing the steering boxes to fail. Mine started to show early signs of failing while I was still stock and now 30k miles later its toast 25k miles on the lift.

Would I do it again absolutely.
