Sort of. The available travel of the
dampers isn't really changing. But the car will be higher, so the overall travel of the suspension system will increase. This only works up to a certain point though. If you raise the spring perches too much, the springs will coil bind before they hit the bump stops, and you will start to lose travel in compression.
If you wanted to increase the total damper travel, you would need to change them with longer stroke dampers. This usually means using longer dampers and, in your case, relocating the suspension mounts. I don't really know of anyone who has gone to that extreme and I'm not sure if this is really worth it for what little off-roading you're going to be doing either.
But in reality I'm rising perches by 0.5 inches so that should not make coils to collide. I measured the diameter of the wire and multiplied it by the # of loops and found that the length of compressed spring is less than the length of damper+bumper by about 1+ inch. I know that bumpers also can compress but I highly doubt that they will ever compress by more than 0.5 in.
