Do I need a snubber on a 8 3/4 rear end?

Some say snubber is a integral part of your suspension althought I purchased a threaded adjustable one from Mancini looks beefy and cool but i ended up backing it all the way out because I dont want to hear the snubber smashing a hole in the floor every time you launch the car or hit a bump? Maybe if you are planning on racing the car
