THE PERFECT FIT

Suspension Quick Set-Up Guide

Accessory rear shock springs are available for riders of different 
weights. A corresponding gauge is available for each spring type. 

The gauge provided with your snowmobile is calibrated for the stock 
spring, which should be used by most riders. Do not change springs 
unless your weight is at the very high or very low end of the stock spring 
rider weight range and adjustments to the factory-installed spring have 
not perfected your ride.

In the following spring guide, the dimension is as measured from the 
spring retainer to the junction of the shock body and end cap. See page 
46.

THE PERFECT FIT

Front Suspension Adjustments

Independent Front Suspension (IFS)

Factory settings, combined with user adjustments to the rear shock 
spring, should be all that’s necessary to provide the best riding experi-
ence for most riders. If all rear shock spring adjustments have been 
exhausted and rider weight is at the very high or very low weight range 
for the stock spring, additional adjustments are possible to the IFS.

Settings will vary from rider to rider, depending on rider weight, vehicle 
speed, riding style, and trail conditions. We recommend starting with 
factory settings and then customizing each adjustment individually to 
suit rider preference. The snowmobile should be methodically tested, 
one change at a time, under the same conditions (trail and snow condi-
tions, vehicle speed, riding position, etc.) after each adjustment until the 
best ride is achieved. 

Break in the suspension for about 150 miles (240 km) before making 
adjustments to the front suspension.

2. Front shocks and springs

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.
