Hello, You are looking at a pair of Fox ski shocks off of a 95 XLT 600 598cc snowmobile (wedge chassis). They are in good used condition. Do not know if they will need to be recharged/rebuilt or not. From center of eye to center of eye they measure 18″. Come 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!
