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. 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 set-
tings, 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: Some models do not have shocks with thread adjustable spring
preload. See your dealer for more information.
CAUTION
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.
