Hello You are looking at a pair of rear suspension HPG shocks off a 1995 Formula SS 670 L/C oil injected snowmobile. They are in good used condition. Do have slight pitting on shafts. From center of eye to center of eye they measure 13 3/4″. Removed from a running sled. Comes as pictured. Pics show condition well. If you have any questions please feel free to ask. Thank you!
