I have an 08 LE 4x4 with a 2" leveling kit. I am getting a little CB contact and I'd like to get another inch. My questions are can I install the 3" kit with the UCA's and get no CB contact? I'm reading some conflicting info that the 08+ Titans will get contact even with the RC upper control arms. Last, I'm on a bit of a budget(boat gas is going to be expensive this summer) so I'd rather not pop for some bilsteins. What are your thoughts on the Rough Country Nitro 9000 shocks? Substantial upgrade over stock?
