No, they are a cosmetic device only. On my previous F250, when i took out hitch always put them in, then saw many more trucks without them. Stopped using them, never gave it another thought for 3 years. New truck now, put the covers in plastic bag under rear seat. Replacements are not worth the cost IMHO.
