WARNING
Suspension adjustment could af-
fect vehicle handling. Always take
time to familiarize yourself with
the vehicle's behavior after any
suspension adjustment have been
made.
Snowmobile handling and comfort de-
pend upon suspension adjustments.
Choice of suspension adjustments
vary with carrying load, driver's weight,
personal preference, riding speed and
field condition.
NOTE: Some adjustments may not
apply to your snowmobile. Use spe-
cial keys in tool kit.
WARNING
Before proceeding with any sus-
pension adjustment, remember:
– Park in a safe place.
– Remove the tether cord cap
(DESS key).
– Lift the front of vehicle off the
ground with a suitable lifting
device before adjusting suspen-
sion.
– Lift rear of vehicle off the ground
with a wide-base snowmobile
stand with a rear deflector pan-
el.
– Make sure lifting device is stable
and secure.
WARNING
Do not attempt to lift the vehicle
by hand alone. Use appropriate
lifting device to avoid risk of strain
injuries.
NOTE: Some models may come from
factory equipped with Take/Apart
(T/A) shocks. These can be rebuilt
or re-calibrated. See an authorized
SKI-DOO dealer.

SC-5 REAR SUSPENSION
1. Rear springs adjustable cams for comfort
and ride height
2. Center spring for steering behavior
3. Stopper strap for snowmobile weight
transfer
4. Coupling blocks — handling
5. Rear shock motion ratio — damping strength
(not adjustable on all models)
Following are guidelines to fine-tune
suspension.
The best way to set up the suspen-
sion, is to start from factory settings,
then customize each adjustment one
at a time. It may be necessary to read-
just center spring after adjusting front
springs for instance. Test run the
snowmobile under the same condi-
tions; trail, speed, snow, driver riding
position, etc. Change one adjustment
and retest. Proceed methodically until
you are satisfied.
NOTICE
Whenever adjusting rear
suspension, check track tension and
adjust as necessary.
Slight suspension bottoming occurring
under the worst riding conditions indi-
cates a good choice of spring preload.
Air Suspension
GTX SE Model
The operator can adjust the comfort
and ride height by adjusting the air
pressure inside the air shock absorber.
