Well when I sit on my raptor the rear shock might as well be bottomed out I weigh about 300 so I just figured finding a used tcs shock would be good enough to have rebuilt and revavlved for my weight I seen a tcs rear shock that came with the linkage on eBay a couple of weeks ago I think it went for around 300 but Unfortunatly I made the mistake of not plugging my computer in before the bidding frenzy lol and I can't seem to find any others
