Hi, I am new to the forum and am planning to get a lift on my 2012 Ram CC 4x4. I am still in my deciding phase of lifting my 4x4.. was thinking 4" and not sure of a 6" lift.. I think the RC brand it the one I want. I am concerned about vibration in the 6"... I also noticed some comments on whell spacers to bring your tires out a bit from the wells.. My question on this is, am I able to do this to mine even though it is not lifted yet? My tires are not as wide but they are taller than factory.. as originally they were 17" and I upgraded rims and wheels to 18" , taller and wider. I would like them to sit outside the wheel well more and have an aggressive look.. What 1.5" spacers can i get and would i have to get an alignment after? Thanks for any input.
