S&S, 4" BORE PISTON RINGS SET. STD
S&S chr/moly replacement piston ring set. Fits all S&S 4" bore Super Sidewinders (incl. TC). Std cyl. bore: 4.00" (101.60mm). 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.
