So I am going to buy a 2015 1500 Silverado LT and wanted to level the truck via rear shackles just because it will make it look better; but I have been reading about a few issues on this topic such as the bump stops bottoming out, the truck making some funny noises when going in reverse due to some sort of banging caused by the shackle drop, and also having to install shims due to the changing of an angle of some mechanical part( I know nothing about trucks or auto mechanics in general); I just wanted some advice from the guys who have done this type of drop on 2014+ trucks and wanted to know if yall could shed some light on these issues stated above or on any issues yall have had encountered along the way. My main concern is that I don't want to ruin a brand new truck.
