Won't hurt anything, I have them on my bowtech. Keep in mind it's been my experience that limb savers don't always make a bow more quiet, but they do effect the amount of hand shock and jump. I would put them on a bow even if I didn't think it needed them because quite simply they work. They soak up vibration and the less vibration the longer your bow will last. And if you were to accidentally dry fire it the limb savers could do just that, save your limbs.
