Welcome from Houston!
Your need for bump stops is determined solely by your right foot and knowledge of the terrain you are on. I have attended several Raptor events with a completely stock truck (plus some off-roading on my own) with no frame issues. If you want to go harder than what the truck is capable of stock (based on your mods, I am guessing the answer to that is yes) than a bump stop kit would be a worthwhile investment.
