When I put my leveling blocks on I think they were bigger than the advertised 2". My truck sits with the front just a tick higher when unloaded and when I hook to my stock trailer it sits alot lower in the back, effects the ride, and looks ridiculous. I think I need a little more than an add-a-leaf because I don't care if the back end sits a little higher than the front. I was thinking about getting blocks to replace the factory ones that were an inch taller. What do you guys think? Has anyone had this problem? Also I don't have helper springs and I need them. I was looking at air bags being that they aren't that much more than regular helpers. Has anyone used them? Is spending the extra money to be able to adjust them in the cab or just get the auto level kit?
