On standard models, the rear arm shock
absorber spring influences the load carry-
ing capability of the snowmobile and
should be adjusted for the weight and rid-
ing preference of the operator.
NOTE: On Sno Pro models with a
rear arm float shock, this adjustment
is achieved by increasingly or
decreasing the air pressure in the
rear arm air shock absorber.
Adjusting Front (Ski)
Shock Springs
The front (ski) shock springs are individu-
ally adjustable for the terrain conditions and
driving style of the operator. The spring
adjuster nut has been set at the factory so the
correct amount of threads are exposed
between the adjuster nut and the threaded
shock body as an initial setting. Additional
ski pressure can be obtained by tightening
the spring tension; ski pressure can be
decreased by relaxing spring tension.
NOTE: Equal adjustments should
be maintained on both sides of the
snowmobile.
Front (ski) shock spring pre-load adjust-
ment is accomplished by loosening the
adjuster nut locking collar (B) from the
adjuster nut (A) and using the Spring
Adjuster Tool from the tool kit, rotating
the adjuster nut in whichever direction is
desired. Tighten the locking collar
against the adjuster nut.

On limited models, use the adjustment
lever located above the EVOL chamber
on the shock to adjust the damping
between settings 1, 2, or 3.

Adjusting Fox Air Shocks
(Sno Pro Models)
NOTE: It is recommended to moni-
tor the air pressure in the air shocks
once every month.
NOTE: Adjusting air shocks may
be done by the snowmobile owner if
qualified to do so. If the owner does
not feel qualified, take the snowmo-
bile to an authorized Arctic Cat
Snowmobile dealer for this service.
This service is at the discretion and
expense of the snowmobile owner.
The air shocks are individually adjustable
for the terrain conditions and driving style
of the operator. The shocks are preset at the
factory (see chart) as an initial setting;
however, it is possible to “fine tune” the
shocks to match the operator’s weight, rid-
ing style, and terrain conditions.
NOTE: Adding air pressure will
increase the air spring force; reduc-
ing air pressure will decrease air
spring force.
Checking and adjusting air pressure must be
done at riding temperature (outside). Also, it
is advisable to check air pressure when the
outside temperature varies more than 25°.
