With the factory height springs (new), 4plusproducts u-bolt flip kit and Boss air bags, there is not much/no room for travel between the top of the u-bolts and the frame. Attached pictures show at 20 psi and again at 0 psi. At 0 psi, it's like riding on the bump stops. At 20 psi, it's better but maybe firmer than it needs to be. I do not know enough to compare spring rebound to air bag rebound, but I am considering going with the lowest lift, 2"-3" to create more space between the springs and the frame and using the air bags for extra load. Will an OME/Dobinson soft 2"-3" lift with very little pressure in bags ride better than factory springs with 20 psi to 30 psi in the bags?
