Stock chain sliders are still available from dealership for less than  $20 i bought a new one for my 85 lt250r and my 86 lt230.  The frame chain roller was available as well but i went aftermarket on that.  As far your other swing arm someone else will have to clue you in.

Yah I do know the oem slider is available, and that will be just fine for my stock swingarm. But I am wondering if there is any other options and if anyone knows what was used on the laegers/lonestar swingarm. The stock fits but doesn't seem proper.

Yah I will have to call laegers, they are definitely still around and making stuff. Not lt250r a arms or swingsrms, but i got my a arm bushings formy laegers arms from them. I will call them tomorrow again. I have called lonestar already and they told me the stock lt500 slider is what they used but that's not possible.

I have dug pretty deep already into this but im just tryng to see if any guys out there maybe used a slider from a diferent model quad like a banshee or something with their aftermsrket swingarms.
