This kit fits 300 Fourtrax, 350 Rancher, 350D Foreman and 400/450 Foreman. We recommend replacing the clutch fibers if unsure of age of the current plates or if they have a hard or slick (glazed) surface. Our clutch plate kits are Japanese made OEM style fibers. Normally your steels are fine to reuse if they aren't discolored from heat. The steels don't typically wear beyond use but if they have been hot more than likely they are warped. If reusing your steels we recommend scuffing them with sandpaper/emory cloth to clean the surface. *Pic may not show the correct plate count as there are different amounts between machines.
