Nope u can set it back to factory settings if u trade it in.

I wondered the same about 33s harming the rig, the only thing it harms is mpg's. Performance wise not sluggish after procal was used.

Once u get 35s and up thats when u need to worry about replacibg certain parts to prevent harming the jeep.
