lol! It's hard to believe it could flex less, but it's true.
The main thing, Dave, is to be able to hit obstacles as "hard" as I need to in 2WD and not overly fatigue the t-bars. I think most of the damage to the stock ones occured BEFORE I put the Ranchos on. I was offroading with basically "blown" factory shocks which would have caused the front end to cycle too much on changes. Were I a 4x4, I would not need quite the momentum I often do.
My thought is, regardless of the "flex" issue, is that the stiffer bars would be more likely to stand up to the abuse for a longer time.
