I have had Bilsteins on my last 5 trucks and have not bottomed out on the shocks. If you are doing this you are grossly overloaded. The frame stops are NOT there for weight control.
[/ QUOTE ]Of course not, but I ocassionally tow on some pretty rough roads. A large bump or pot hole, could cause the springs to bottom with a heavy load. I installed air bags to prevent this, as I do like the shocks. My feeling is, that if the shocks are properly designed for the application, they will be able to handle the full travel of the suspension. The real solution isn't air bags or overload springs. It's more lift under the rear springs.
