Correct Track will add leverage to the spring hanger. I had one almost rip the hanger off in an emergency braking incident. I took them off and had MORryde install riser tubes. LT215/85-16 tires will add some height--I used them on the trailer with 33" spacing. Of course that depends on the OP being willing to use LT instead of ST. A sub-frame is by far the strongest. The MORryde SRE4000 equalizer will raise the trailer about 1" and give a smoother ride to the trailer at the same time. The SRE4000 needs 3" of clearance before installation (after larger tires).
