Wht is the purpose of air bags? It appears that they are mostly added when someone is nose heavy or overweight for the their truck. True or not? Benefits or reasons to avoid? Thanks!
There is a big difference between increasing carrying capacity and increasing GVWR. You can easily increase the suspension capacity, but that is not going to do anything to help the axle, brake, frame or tire capacities. GVWR is a rating placed on the vehicle as a complete system by the manufacturer and simply adding spring capacity is not going to change that.
