I found these instructions for the Service kit installation of this in a for sale thread on this site. These were for Dealer service campaign. If you read it says under full vehicle weight the stop should be tightened with 1/8" of space to the spring. This is with factory spring geometry but it seems too close to me. I would think you would get hard contact and banging under fast spring compression at least looking at the spring geometry of the ORD / Alcan custom springs. They are designed with that thinner gauge higher leaf count so they do deflect a lot more than factory set up.

Anyways food for thought ...
