THE PERFECT FIT
Front Suspension Adjustments
IFS Shock Spring Preload
Increasing spring preload will increase ski-
to-ground pressure. Decreasing spring pre-
load 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.
Always perform shock spring preload
adjustments with the weight of the vehicle
removed from the shock and with the shock
at full extension.
To change shock spring preload, grasp the
spring retainer 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 (2.54
cm) of preload beyond the factory settings.
NOTICE: 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:Other spring options are available. Please see your POLARIS dealer.
