My personal and expensive experience in my 2012 on top perch. Do not do it. 2012 and up on top perch or leveling kit (with or without aftermarket upper control arms) WILL destroy cv boots/shafts! The torsen and top perch/leveling kit do NOT play nice together. It puts the cv joints close to bind angles at full droop/full lock of steering wheel. You can away with it if you do not use 4wd. Once you shift into 4wd and the cv joints start spinning, it will pinch and destroy the cv boot.
