In the pro ride forum, it seems like this is the only aftermarket belt worth a darn for the pro rmk's, guys are saying it's better than the stock belt but costs quite a bit less. I recently purchased a pro and I'm gonna be trying one out. My question Is, have any of you guys used one in your edge sleds? My dad has an 04 escape and we are curious if it is worth trying out for his sled too? A Google search found that the part number for the edge version of the belt is 48c4553, is this correct?
