THE PERFECT FIT
IQ Front Suspension Adjustments
Front 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 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
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
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.
Tip: Not all models have shocks with thread-adjustable spring preload. See your
dealer for more information.
NOTICE: 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 suddenly increases while you’re turning it.
