Thanks for the add. I"m having issues with a differential drop kit installation on my 2020 Z71. I did the 3inch leveling kit in the front and 3-inch Rouch Country blocks in the rear. I also added the Rough Country upper control arms. However, I do get a lot of vibration at low speeds. I can't find any install videos on the differential drop kit. This kit should lessen my cv angles, curing my vibration issue. Any help would be appreciated.
