THE PERFECT FIT
Suspension Quick Set-Up Guide
Rear Track Shock Spring Settings
For riders who weigh 160-220 lbs. (73-100 kg), test ride at factory
settings, then make fine-tuning adjustments. See page 71.
For riders outside the 160-220 lbs. (73-100 kg) weight range, adjust the
factory-set preload to the following installed lengths as a starting point,
then test ride before making fine-tuning adjustments. Do not exceed the
minimum and maximum installed length requirements. See page 71.
Always perform shock spring preload adjustments with the weight of the
vehicle removed from the shock and with the shock at full extension.
If adjustments to the factory-installed springs are not sufficient for
riders over 300 lbs. (136 kg), optional stiffer springs are available.
Please see your POLARIS dealer.
