I emailed Deaver, they called me back and laid it all out for me. The deavers are meant to replace the overload leaf. In turn they are there to allow more travel when offroading. BUT....BUT! Leaving the overload spring in will not hurt anything or damadge the deaver mini pack. So its up to all of you. Im leaving it in for my trip to TN. See how it goes, and make up my mind then. But either way, IT DOESNT HURT YOU AT ALL. If i was using the rig to just offroad every other day id take em out for sure. But right now there isnt a big enough reason to take em out.
