S&S chr/moly replacement piston ring set. Fits all S&S 4-1/8" bore Super Sidewinder Plus (incl. TC). Std cyl. bore: 4.25" (107.95mm). Note compression ring gap: To determine the correct ring gap on your newly installed piston rings is very important. A too narrow gap may result in premature piston ring/cylinder wall wear or even seizure, possibly breaking rings and/or damage to pistons and/or cylinder walls, and so on. A piston ring gap that is wider than necessary will result in needless compression loss and reduced engine efficiency. Recommended ring gap is .004" per inch of cylinder diameter for street engines. For a 3-5/8" (3.625") bore engine piston ring gap would be 3.625" x .004" = .0145". (.0145" x 25.4 = 0.3683mm or, when rounded of, 0.37mm). Information provided by S&S Cycle, Inc. Fits: > All S&S SSW+ engines (Evo & Twin Cam style)

It's not difficult to determine if a Hastings piston ring set will fit a certain piston. You should measure the height of the piston groove in the piston itself. The 2 top grooves will be for compression rings, the lower groove will be for the oil ring. In most cases Hastings oil rings are of the low tension 3-piece flex vent type. Ring heights are listed for reference. Tech tip: Piston oversizes. For each oversize cylinder diameter will increase with .010" (0.254mm). The standard bore of the cylinder is listed for reference.
