If a new spring is being used to level the truck then it will give increased travel. If it is one of the discs that is inserted above the stock spring then the travel will not be increased as it is the same spring. However, in your case, if it is the disc . . . it is fairly easy to remove. If it is a new spring, you will need to find or purchase a new stock spring to replace the leveling spring. I would say that the latter is not worth the effort.
