Unfortunately the hanger needs to be moved or the spring de-arched to make it longer at rest. If just hitting the shackle to move it with a load on it. As soon as unloaded such as going over a bump the spring will pull shackle back as it is now and next bump will invert it to the frame. With a compression shackle as you have the shackle must be in the rear path with the spring unloaded. Make sense? Just trying to help you understand how it will work.
