I have got to add new shocks to the rhino. The old ones have about 4200 miles and are completely shot. They are the standard ones. I was going to replace with the progressive shocks all the way around. I only carry the wife and myself, cooler, gas can, and about 50 extra lbs of crap that the wife has to bring. Should I replace with the HD or standard progressive shocks. I do ride pretty hard.
