ing is needed after you have exhausted all possible adjustments to the 

rear shock spring and clicker, refer to the information on the following 

pages of this manual.

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.

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.

Front Suspension Adjustments

IFS Shock Compression Damping

Make adjustments to the shock clickers to control bottoming. Make the 

adjustments in 1-to-2-click increments, then test ride. Repeat the adjust-

ment until the desired result is achieved.

TIP: Initially, heavier riders may want to set the shock clickers 2-4 clicks higher 

than lighter riders.

The standard clicker setting is 6 clicks 

from the softest position. 
• Turn the clicker clockwise for a 

stiffer ride (as viewed from the top).

• Turn the clicker counter-clockwise 

for a softer ride.

When adjusting, we recommend that 

you turn the clicker only one or two 

clicks, then test ride. Always adjust 

both shocks equally.

Shock Valving

Some shocks can be revalved if spring 

preload alone isn't sufficient and fur-

ther adjustment is desired to control 

suspension stiffness. Please see your 

Polaris dealer.

WARNING! Changing shock valving requires special tools and a sound 

knowledge of mechanical theory, tool use, and shop procedures to perform the 

work safely and correctly. Shocks contain high-pressure nitrogen gas. Use 

extreme caution when handling high-pressure service equipment. We 

recommend that this work be performed by a Polaris dealer.
