THE PERFECT FIT
Front Suspension Adjustments
IFS 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.
The initial IFS preload setting is 3 3/4
inches (9.5 cm) from body end to retainer.
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 set-
tings.
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.
