Medium duty coils should be fine. I regularly hang my dirtbike off the back of mine(which has rear medium duty coils, I don't think they make HD rears?) with one of those hitch carriers. I also did it while I was at stock height, which I believe the OEM coils are not rated as high as the medium duty OME coils. You'll be fine, get out there and enjoy riding.

You can get HD OME springs for the front (927's) or the 790's if you have a diesel or are planning on adding a heavy front bumper like an ARB. You should be fine with that carrier; I regularly tow a bass boat that has a heavy galvanized trailer and the rear barely moves when I hang the trailer on the hitch. I'm running the OME 948 MD springs.
