Additional InfoĀ
Why did Pacbrake add a bump stop to their bags?
Peace of mind.Ā Customers want a bump stop to prevent bottoming out from loss of air bag pressure, an extremely rare event that could damage the airbags or potentially the frame of the truck. Think of it asĀ an "insurance policy" against bottoming out.
An additional benefit is that you can run these airbags at 0 psi when unloaded for superior ride comfort.
Are bump stops necessary?
No! For those that require max travelĀ in their air bags, to raise and lower their rear end to pickup trailers or boats, or for those that take their trucks off-roading,Ā air bags without bump stops are recommended. Consider the HP10585-X ALPHA XDĀ air bag.
