If you look between your frame and the spring , you will see the "X" has dual bump stops. Totally remove the forward stop that hits the spring before the axle. This is a bolt on item. Then take the bump stop that is directly over the axle tube, remove them. Take one of these to you local 4wd parts store and have them find you a pair of low profile urethane pads that will bolt on in their place. You can drive around with out the stops, without causing any damage. If you should hit a speed bump or such it will hit metal to metal and be noisy. It will not do serious damage. This is how I set up the rear on my XterraRacer. If you do lots of serious off roading then you may look at doing the add-a-leaf or a new spring pack. Your stops will already be set up for more movement.
