SUSPENSION STIFFENING KITS (F-Chassis Models)

The front and rear suspensions have been calibrated for a rider weight range of 180 to 200 lb. If a firmer ride is 
desired, there are two kits available to stiffen the suspensions on these models by 20 percent. It is important to 
order the correct kit because these kits do not interchange. Do not use the standard model kit on the Sno Pro model 
because the shocks are different on these two models. The two stiffening kits include everything required and the 
part numbers are as follows:
