Hello, You are looking at a pair of suspension shock brackets removed from a 93 Mach 1 670 snowmobile. It is not the original shock support brackets for this sled. Someone put a newer suspension in it. I did some research on a parts fiche and it looks like it may be off a 97 MXZ 583/670 or a 98 MXZ 500. They are in good used condition. 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!
