What setting do you have your springs set at? I just checked mine and I have an inch or more of clearance. Are you talking when the suspension is fully compressed, like carrying a heavy load? I think that is the only time it should ever rub if it is going to rub. I have my springs up to the 4th setting all around and they have never rubbed. So to answer your question, no, it is not normal for it to rub. Nothing should be rubbing or binding anywhere. Give us more details on exactly what you mean? Fully loaded(springs compressed?) or unloaded(springs at rest?)........Irv
