Here is a pair of used Cylinders with Pistons and rings from a 1979 Arctic Cat 340 Jag Snowmobile.  These Cylinders came from a healthy motor.  This motor had excellent compression.  These measure 60mm which is standard.  These cylinder walls are smooth and have no damage.  You can see lines of wear and use, but you cannot feel them.  Smooth and nice.  Pistons are in great shape as well.  Please look the large pictures over good.  You'll receive exactly what is pictured.  This MIGHT fit the 1977 1978 1980 Jag or possibly Lynx sleds.  

                                          PLEASE, check with your local dealer to be sure it fits your model Arctic Cat Snowmobile.
