Adjusting Rear Spring
Pre-Load
Proper adjustment of rear spring pre-
load is necessary to get the most com-
fortable ride. The chart is designed to
help in setting up rear spring pre-load;
however, riding style is the single
greatest factor in determining rear
spring requirements.

 NOTE: These cam position set-
tings are suggestions only. Per-
sonal riding style will greatly
influence cam position settings.
Spend time to determine setting
preferences.
Rear spring pre-load adjustment is
accomplished by rotating the adjusting
cams. Position 3 provides the stiffest
ride, and position 1 is for the light
driver or slow-speed trail riding. Posi-
tion 2 is for the average operator under
normal conditions. Always rotate the
cam from the lighter position to the
heavier position.
! CAUTION
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.
Articulating Skid
Frame (Bearcat XT
Models)
The rear articulating portion of the skid
frame has two adjusters which control
the amount of travel in the rear suspen-
sion.
These two adjusters have been pre-set
at the factory and should require no
further adjustment.
If adjustment is ever required, rotate
the two adjusters equally to permit
12.5-25 mm (1/2-1 in.) travel of the
articulating portion of the suspension.
Overload Springs
Some models have overload springs
built into the rear suspension. When
either carrying a heavy load or riding
2-up, the overload springs should be
engaged by rotating the spring tension
blocks to the UP position. The spring
tension blocks lock in an over-center
position when engaged.
 NOTE: Arctic Cat recommends
that the overload
engaged whenever a load on the
snowmobile (operator/passenger/
cargo) exceeds 136 kg (300 lb).
