I parted out a 1994 Ski-Doo Formula STX 583. This was a complete running and rideable sled that I was unable to sell to anyone whole , so I parted it out. Just before I listed the whole sled for sale, I had a brand new aftermarket seat cover put on it. The seat was used 20 miles , tops , after recovering before it was pulled off and put into safe and dry storage.
Nice and soft and flexible. Fits F-chassis snowmobiles from 1993 - 2000. At the photo closely to make sure it's what you need.
Or try to call a dealer. I also will help in any way possible to verify this fits your sled.
