Hey all. I'm trying to find out how much a stock 660 or 700 shock/spring combo will hold up in direct compression? Our atv's weight will not work well because of the fulcrum setup our quads use. I working on a project they may work for but they need to hold up a snowmobile with 300lb rider and another 200-300 lbs of equipment. I'd like to do it in 4 shocks, but could use 8 if I had too. Thinking of stock quad shocks because they are cheap. Thanks!
