I bought a rear skid and track off craigslist for 200 bucks. it's a 162" and I think it's a 01-3 rmk I have it under my 92 polaris rt now I measured the hole mount 7x before I drilled and installed. and now that I have the whole rear end under it I can't get it to compress more than a inch. at first I went throu and tightened all the bolts it took we a few hours to realize I over tightened the sissors and pivot points. now it only moves 1 ". I do believe it has fat boy springs on it ! all grease fittings are greesed and move with no binding so what's not giving !??!?
