My '85 Burb has a flip kit in the rear and I have about 1.5" between the axle and frame, no notch....yet, and I have air shocks installed for ease. They do really help with big loads or a trailer. I've had some loads of people/junk in it and they really help with towing the boat. It is a poor mans fix for sure, I plan on installing air ride in the rear in the spring/summer just because I think it would be better. The air shocks are a temp. fix. for me but if you need them JUST for towing a trailer, do it. You can get a decent set for around $80 or so, far cheaper than an air ride set up, even with manual fill valves, etc.
