I have done the same adjustment of trailer ride height. The shocks have a stud on each end that is long enough to install a 5/8 inch tubing spacer first, then the washer, rubber donut, through the shock mount, second rubber donut, second washer and finally the nut. I did this on each end of the shock and it has worked well for several thousand miles.

This makes the trailer ride level and adds some clearnace for the skid plates to the road in the back. I also welded on 2 inch steel rollers to the bicycle rack receiver for those road dips that make the back end drag. I can tell by the wear pattern on the wheels that they have been used a few times.
