Rebuild
If you've tried all of these tuning tips and just aren't getting the right performance out of your shocks that you think you should be getting or you fall outside the industry average of a 160-pound casual-aggressive rider, then you should have your shocks rebuilt by someone who knows what they're doing. Many dealerships can either rebuild the shocks in-house or pull them off the sled for you and send them to someone who can. The other option is to remove the shocks from the front end and the skid frame yourself and take or ship them somewhere. Tom's Snowmobile Service is the Factory Connection of snowmobiling. You can ship your shocks to Tom's, along with your weight and riding style and they will rebuild them and ship them back. Tom's specializes in Fox; there are other shops that specialize in Walker Evans, Kayaba (KYB), Ryde FX, Ohlins, Exit and other shock brands. You can even go with coil spring upgrades, like RCS titanium springs.
