I've got a 4 in RC lift on my Tahoe and I'm slightly rubbing but I need only about an inch extra to clear my front tires. This wouldn't be much of a problem if I didn't have an aftermarket bumper because I could just add a 2in body lift but unfortunately I wouldn't be able to relocate the bumper so there would be the ugly gap up front! Is there any other way I could add a little more height to the front without having to go out and buy a 6in suspension lift??
