Always verify ski
alignment before making adjustments to the IFS. See
Ski
Alignment 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.
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,
your POLARIS dealer can assist..
