TUNE YOUR RIDE
Rear Springs
Rear spring preload has an effect on
comfort, ride height and load compen-
sation.
Also, adjusting rear spring preload
shifts more or less weight to the snow-
mobile front end. As a result, more or
less weight is applied to the skis. This
has an effect on performance in deep
snow, steering effort and handling.
Slight suspension bottoming occurring
under the worst riding conditions indi-
cates a good choice of spring preload.
ACTION RESULT
Firmer rear suspension
Higher rear end
More bump absorption
capability
Increasing
preload
Heavier steering
Softer rear suspension
Lower rear end
Less bump absorption
capability
Lighter steering
Decreasing
preload
Better performance and
handling in deep snow
Refer to the following to determine if
preload is correct.

TYPICAL — PROPER ADJUSTMENT
A. Suspension fully extended
B. Suspension has collapsed with driver,
passenger(s) and load added
C. Distance between dimension “A” and “B”,
see table below
”C” WHAT TO DO
50 to
75 mm
(2 to 3 in)
No adjustment required
More than
75 mm
(3 in)
Adjusted too soft,
increase preload
Less than
50 mm
(2 in)
Adjusted too firm,
decrease preload
NOTE: If the specification is unattain-
able with the original springs, see an
authorized Ski-Doo dealer for other
available springs.
NOTICE
To increase spring
preload, always turn the left side
adjustment cam in a clockwise di-
rection, and the right side cam in a
counterclockwise direction.
CAUTION Never set preload
cams directly from position 5 to 1 or
directly from position 1 to 5.
The adjustment cams have 5 different
settings, 1 being the softest.
