i run 25psi in the desert.. you want the tire as well as the suspension to absorb the terrain.. 40psi even on the street is ridiculous..
i have RPG full tie rods, and haven't had any issues with breaking anything.. plenty of off road driving, snow, sand, desert..
I mostly got them for the bling.. i was just gonna get the half outer tie rod, you really cant even see the half outer unless you get under there..
it does not take long to change an inner on the trail, provided there is a spare available...
really, if youre gonna off road your truck, these things are kind of expected, and if you search this forum there has been plenty of bent inner tie rod issues. im very surprised they'd even mention covering it, i bet they are going to eat it later..
