Depends on how you level. If Billsteins, then almost no one has had issues, up to 2.1, and so very few, as to be unworthy of notice, have had soem issues, at 2.8.
However, when I did my Bills, I went with 2.1 and got Mevotechs. For the best reason of all. I only wanted to mess with it, once, AND< I ma the not the guy who wins the lottery. my luck tends to go in the other direction.
My single greatest concern was the slight wobble, again so few mentioned it that is unworthy of notice, some have mentioned, at highway speeds and at 2.8 setting. Hence. 2.1 for me
Did not see any sense to raise my front end, to 2.8, gain 0.7 inches, only to have to add a spacer, to teh rear, to make it look right.
2.1 left me enough slight rake that my truck looks level, nto nose high as a truly level tends to appear, and I have no worries aoubt 4x4 highway speed wobbles or my UCA being stressed.
so, after all this, yes, upgrade to mevotechs, you are already in there, cheap $100 inusrance. go with billsteins set to 2.1 and leave the rear spacer out of the equation.
