Hello, You are looking at a pair of Fox ski shocks with no springs off a 98 XC 600 Twin snowmobile. They are in used condition. The top of the shocks (where the top bushings go) are bent as seen in pics. Do not know if they will need to be rebuilt or not, but they do have pressure and compress and decompress on their own. From center of eye to center of eye they measure 15.75″. 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. Thank you!
