After doing a bit of research I decided on this kit to lift my 2014 Ram 1500 4x4. The kit wasn't difficult to put in, did it over a weekend. The lift is very noticeable and you have to get accustomed to getting in and hopping out once kit is in. Also purchased Bilstein Shock Absorber B8 for the Rear which kept the ride smooth with the lift. I haven't had the issue with the axle boot rubbing, actually had no issues for the past 2 years since its been on.
