What should the ski stance be on an 02 edge 800 xcsp?Mine is measuring 50" from outside edge to outside edge and I'm having a heck of a time finding aluminum ramps that are wide enough.

50" is not likely stock. Betting it's had some kind of kit installed on it to make it that way. Stance is usually measured center to center. That should be close to 42.5" according to specs. Add for the width of the skis, and that should leave you somewhere just a shade over 47" I think.

Mine is also around 50 and its stock. 42.5 is the stock stance center to center, but if your sled's suspension sags in the front end the stance will widen a couple of inches because of the control arms straightening out.
