I installed Bilsteins set at 2.8 on my 2011 Ram Sport today. Truck looks great but I now have a vibration in 4WD when I accelerate fast from 0-40. It only seems to do it in 4WD. I ordered new wheels and 35x12.5x20 Trail Grapplers which have not come in yet. Once I get everything set up i will do an Alignment and hopefully that will fix the problem? Anyone else have this trouble and find a solution? If the vibration is still there will it cause damage to my truck in the long run? I'm kind of wishing i went with the 2.1 setting now but I also read others have had the same issue with the 2.1 setting.
