Hello I recently purchased a 2017 Ram Laramie crew cab. The dealership threw in a set of 275/65r20 BFG k02 tires on the deal. The tires are being put on in a few days. I ordered front and rear 5100s for the truck but after doing research like everyone else I have seen that some people have vibrations in 4x4 on dry pavement. I know this has been addressed many times but I can not seem to find anyone that has done the 1.4" adjustment. Iv noticed many go with the 2.8 and some with the 2.1. Has anyone on here went with the 1.4" adjustment? If so how do you like it? Did it fix the Vibration Problem? Also should I go with the 1.4 or the 2.1 and should I buy the mevotech Upper control arms?
