Front Suspension Adjustments

Spring Preload

Increasing spring preload will increase
ski-to-ground pressure. Decreasing
spring preload will decrease ski-to-
ground pressure. When adjusting, be
sure the springs on both the left and right
sides of the machine are at the same
adjustment.
To increase front shock spring preload,
grasp the spring and turn it to the right.
Turn it to the left to decrease preload.
Increasing the spring preload too much
may adversely affect the handling of the
snowmobile and the performance of the
suspension. Never exceed one inch of
preload beyond the factory settings, and
ensure that both sides are adjusted the
same. When decreasing preload, make sure at least two turns of preload
are holding the spring between the retainer on top of the shock and the
threaded spring preload adjuster nut on the shock body.
NOTE: Not all models have shocks with thread adjustable spring pre-
load. See your dealer for more information.
Always leave one thread showing above the adjuster nut. On models
equipped with a plastic adjuster nut, if the nut is unscrewed from the
threaded body, the nut will break.

Front Springs

For models without externally adjustable or revalvable shocks, the front
springs can be changed if spring preload alone isn't sufficient and fur-
ther adjustment is desired to control suspension stiffness. See your
Polaris dealer for more information.
