Suspension
The suspension should be adjusted for
the operational needs and riding prefer-
ence of the operator.
The front shock springs determine the
amount of ski pressure and the reaction
of the front suspension to rough terrain.
The amount of ski pressure can also be
changed by adjusting the length of the
skid frame front arm limiter straps.
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 individ-
ually adjustable for the terrain conditions
and driving style of the operator. The
spring adjuster nut has been set at the fac-
tory 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 pres-
sure 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.

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 pre-
set at the factory (see chart) as an initial
setting; however, it is possible to ““fine
tune”” the shocks to match the operator’’s
weight, riding style, and terrain condi-
tions.
„ 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°.
