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 3.2 mm
(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 snowmobile
are adversely affected.
Adjusting Skid Frame Rear
Shock (Fox QS3)
To adjust the damping, use the adjust-
ment lever located above the EVOL
chamber on the shock. There are three
settings that may be chosen: 1, 2, or 3.
Adjusting Rear Spring Pre-
Load
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 posi-
tion. 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.
