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 pres-
sure. When adjusting, be sure the springs
on both the left and right sides of the
machine are at the same adjustment.
To change front shock spring preload,
grasp the spring and rotate it.
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 pre-
load 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 hold-
ing the spring between the retainer on the
top of the shock and the threaded spring
preload adjuster nut on the shock body. Failure to do so could cause the
retainer to fall off when the suspension is fully extended.
NOTE: Not all models have shocks with thread-adjustable spring pre-
load. See your dealer for more information.
CAUTION
On some models equipped with a plastic adjuster nut, the nut will break if it is
unscrewed from the threaded body. Do not force the nut if resistance sud-
denly increases while you’re turning it.
