Hello, You are looking at a rear suspension front shock off a 2000 Triumph 600 snowmobile. It is in good used working condition. Worked fine on sled. Not sure if it will need recharging or not. Looks good. From center of eye to center of eye it measures about 11″. Should fit several years and models, but please do your own checking to be sure it will fit your sled. If you have any ?’s please feel free to email me. Thank you!
