Yes. Looking from the back of the sled, the scratchers 'splay' outwards. If you take the silver wear piece and move it from the right side of the sled to the left side of the sled you will be exposing fresh material. In
@Phatboyc picture above, the image would be installed on the left hand scratcher (looking from rear) and the blue part would be getting worn. If you then remove that piece and swap it for the one on the right, the green edge would now be down and it would be getting worn. I happen to have an uninstalled set here. The picture below is the left side scratcher as seen from the rear, the right side is a mirror image.
