520935 | Arctic Cat Heavy Duty SProcket/Chain Kit

The 1100 Turbo from Arctic Cat is the most powerful OEM snowmobile engine on the market. To harness that power, we recommend an upgrade to the BorgWarner HY-VO® drive chain and sProckets. With 14% bigger pins than the stock chain, torque capacity and longevity is greatly increased. This conversion is a must have for increased horsepower applications. HY-VO® chains must be used with HY-VO® conversion sProckets. All kits include a BorgWarner HY-VO® chain, a top sProcket and a bottom sProcket. All kits can be used with the stock tensioner.
