Ski-Doo made what is arguably the best snowmobile ever produced in their Gen4 850. However, the OEM suspension on all models leaves a lot to be desired. We offer a number of ski packages utilizing Fox dampers for various budgets and ride charecteristics that vastly improve the ride of the sled.
Air shock for ultimate adjustability. Easily tone the air spring utilizing a shock pump. This allows much more adjustibility than preload alone.
Our Custom Tuned Fox air shocks come in four trim packages
Basic: Fox Float 3 Evol 850 RAS 3
Mid Grade (rebound adjust): Fox Float 3 Evol R
Mid Grade Premium (rebound adjust + Kashima coat): Fox Float 3 Evol R Full Kashima
Top Grade (full adjust): Fox Float 3 Evol QS3-R
The basic kit is only adjustable via air pressure. This kit allows for spring rate adjustment in the main chamber and bottom out adjustment in the EVOL chamber. Compression damping and rebound damping set at our shop for your application.
The Mid Grade kit offers the same adjustment as the the basic kit an external rebound damping adjustment. The mid grade "Kashima" option also features the friction reducing Kashima coat on the air sleeve and body. This coating, an exclusive from Fox, substantially reduces the friction (also known as "stiction") in the system.
Top Grade is fully adjustable. Features adjustable rebound and adjustable low speed compression via a 3 position dial as well as a dedicated piggyback to improve oil flow and damping consistency.
No matter which package you chose, it will be valved for your specific rider weight and intended use. This is what makes Sik Suspension the way to go!
