When my truck sits normal, the rear axle sits slightly lower than the front. It should sit level, then when I put on the boat, it sags even more with the tongue weight. I want the rear to ride about 1-2" high unloaded and level when trailering. Some guys at work that tow race cars said to put and air suspension lift on my shock arms. Anyone ever use these. A gauge in the truck allows you to adjust the ride the way you want it. I don't want to give up the soft ride the Bravada offers, but need a little more beef with a boat on. I'm constantly dragging my swivel jack wheel when going over bumps. The kit is under $100. Plus with the ground effect package on my truck, the tires sit very close to the fender wall, a lift would give a little more clearance. Is it a good investment or should I just put in a standard 2" lift?
