Adjusting Skid Frame
Front Arm
The skid frame front arm shock spring ten-
sion and the limiter straps are adjustable.
However, Arctic Cat recommends that the
shock spring be maintained at the factory
preset of 1/8-1/4 in. preload. Tightening the
skid frame front arm shock spring may
cause improper balance and may ruin the
handling features of the snowmobile.
The length adjustment of the front arm lim-
iter straps determines the weight distribution
between the front of the skid frame and the
skis. Tightening the limiter strap (shortening
the strap) will pull up on the front of the skid
frame and will increase ski pressure. Loos-
ening the limiter strap (lengthening the
strap) lowers the front of the skid frame and
decreases ski pressure.
When customizing the amount of ski
pressure, be sure to adjust both straps
equally and do not over-adjust the limiter
straps to adversely affect steering and
operator control of the snowmobile.
Some experimentation may be required
until the proper adjustment for the opera-
tor's individual style is obtained.

NOTE: If the limiter straps are
adjusted, it is highly recommended that
at least a minimum of 1/8 in. preload on
the shock spring be maintained.
! WARNING
Do not adjust the front arm limiter
straps to a point at which steering
and operator control of the snowmo-
bile are adversely affected.
Adjusting Rear Spring Pre-
Load (ZR)
Proper adjustment of rear spring pre-load
is necessary to get the most desirable
ride. The chart is designed to help in set-
ting up rear spring pre-load; however,
riding style is the single greatest factor in
determining rear spring requirements.

tings are suggestions only. Personal
riding style will greatly influence
cam position settings. Spend time to
determine setting preferences.
Rear spring pre-load adjustment is accom-
plished by rotating the adjusting cams.
Position 3 provides the stiffest ride, and
position 1 is for the light driver or slow-
speed trail riding. Position 2 is for the
average operator under normal conditions.
Always rotate the cam from the lighter
position to the heavier position.
Never force the adjustment cams
from the low position to the high
position. Cam damage may occur.
To rotate an adjusting cam, use the spark
plug wrench from the tool kit. Rotate the
wrench until the cam is in the desired
position. To stiffen the ride, rotate the cam
so as to raise the spring end. Make the
appropriate adjustment on the other cam.
Adjusting Skid Frame Rear
Arm Shock Spring (M/XF)
Proper adjustment of rear arm shock
absorber spring pre-load is necessary to
get the most desirable ride.
The rear arm shock spring is adjustable
for the terrain conditions and driving
style and weight 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.
