Hello, You are looking at a monoblock/cylinders with pistons off a 95 XCR SP 440 snowmobile. They are in good used working condition. Cylinder bores have some minor scuffs as seen in pics. Magnet sticks to cylinders so they are metal. Pistons are ok, one has more scuffing on one side than the other as seen in pics. Removed from a running sled. Comes as pictured. Pics show condition well. Could fit several years and models, but please do your own checking to make sure it will fit your application. If you have any questions please feel free to ask.
