FEATURES AND CONTROLS

Cargo Rack

Always secure cargo before operating. Do not exceed the rack weight

the seat back or the cargo rack.

Whenever towing or operating with a heavy load, place the transmission

THE PERFECT FIT

Front Suspension Adjustments

Break in the suspension for approximately 150 miles (240 km) and re-
grease all suspension parts before making any fine-tuning adjustments.

Settings will vary from rider to rider, depending on rider weight, vehicle 
speed, riding style, and trail conditions. We recommend starting with 
factory settings and then customizing each adjustment individually to 
suit rider preference. The snowmobile should be methodically tested 
under the same conditions after each adjustment (trail and snow 
conditions, vehicle speed, riding position, etc.) until the best ride is 
achieved. Adjustments should be made to one area at a time in order to 
properly evaluate the change.

THE PERFECT FIT

Front Suspension Adjustments

Always verify ski alignment before making adjustments to the IFS. See 
page 93 to check alignment. If the skis are misaligned, see your dealer, 
as the camber adjustment may also be affected.

The tension at which the shock coil spring is set is called spring preload. 
For the best ride, the spring preload should be set as low as possible to 
use the full travel of the ski shock, with occasional light bottoming. To 
determine if your snowmobile is using full travel of the ski shock, push 
the jounce bumper down as far as it will go on the shock rod and test 
ride the snowmobile. The bumper will move up on the rod in direct 
relation to the amount of travel. If the shock travel is full, the bumper 
will be seated at the top of the shock.

THE PERFECT FIT

Front Suspension Adjustments

Shock Spring Preload

Increasing spring preload 
will increase ski-to-ground 
pressure. Decreasing spring 
preload will decrease ski-
to-ground pressure.

Front Springs

For models without 
externally adjustable or 
revalvable shocks, the front 
springs can be changed if 
spring preload alone isn’t 
sufficient and further 
adjustment is desired to 
control suspension 
stiffness. Special tools are 
required to adjust front 
springs. If you feel that 
your front suspension needs 
adjustment see your 
POLARIS dealer for more 
information.
