Extended bump stops on rear axle? Anyone done this?

extending the bump stop May save your tires but it won't do anything for your vertebrae, you will have a ride similar to a hardtail Harley. I have 3 in over Arch HD Springs on my Dart to clear my 275. It's a little higher than I would like

Hoping for a similar rake to your's, I had 3" lift on my 69 dart in the past, want similar on my duster but don't want to rub the tires, surely if the springs have a 3" lift then extending the bump stops a similar or slightly less amount should be fine?
