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.

Rear Suspension Adjustments

Rider weight, riding style, trail conditions, and vehicle speed all affect 
suspension action.

Each rear suspension can be adjusted to suit rider preference and deliver 
excellent performance for a given set of conditions. However, all sus-
pension designs and adjustments involve a compromise, or trade-off. 
For example, a suspension set up for snowcross racing would provide a 
very stiff ride on the trail. A suspension set up for trail riding would bot-
tom out harshly on a snowcross course.

Additional adjustments should be made after initial setup. Make adjust-
ments to one area at a time so you can evaluate the change. For further 
assistance, see your dealer.

Suspension Performance Tips

• Rider weight usually determines the position at which the spring pre-

load should be set. However, this may vary with riding style. With a 
little experimentation, each rider can find a preferred set-up. 

• In deep snow, a new rail slide will offer improved performance over 

worn rail slide. It can also improve top speed.

• When riding on ice or hard-packed snow, adding a set of bogie wheels 

to the rail may enhance the snowmobile's performance. Bogie wheel 
kits are available from your dealer.

Track Tension

Track adjustment is critical for proper handling. Always maintain cor-
rect tension and alignment. Refer to the track tension maintenance sec-
tion beginning on page 106.

Rear Suspension Adjustments

Front Track Shock Compression Damping

Make adjustments to the shock 
clicker to control bottoming. Make 
the adjustments in 2-click incre-
ments, then test ride. Repeat the 
adjustment 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 2 
clicks from the softest position. 

• Turn the clicker clockwise for a 

stiffer ride.

• Turn the clicker counter-clockwise for a softer ride.

Front Track Shock Spring Preload

Always perform shock spring preload adjustments with the weight of 
the vehicle removed from the shock and with the shock at full extension.

Increasing spring preload will decrease ski-to-
ground pressure. Decreasing spring preload 
will increase ski-to-ground pressure.

The initial preload setting is 1.375 inches 
(3.49 cm) from body end to spring. 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 snowmo-
bile and the performance of the suspension. 
Never exceed one inch (2.54 cm) of preload 
beyond the factory settings.

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.

Rear Suspension Adjustments

Rear Shock Spring Preload Settings

Make adjustments to the rear shock spring to tune vehicle balance. 
Always perform shock spring preload adjustments with the weight of 
the vehicle removed from the shock and with the shock at full extension.

Increasing preload will increase ski pressure and result in less weight 
transfer and flatter cornering and more precise steering response. 
Decreasing preload will decrease ski pressure and result in more weight 
transfer, or less weight on the skis when accelerating. 

Turn the spring retainer up to one turn from the initial setting, then test 
ride. Repeat the adjustment in one-turn increments until the desired 
result is achieved.

Increasing the spring preload too much may adversely affect the han-
dling of the snowmobile and the performance of the suspension. Never 
exceed one inch (2.54 cm) of preload beyond the factory settings.

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.

Rear Shock Clicker

Make adjustments to the shock 
clicker to control bottoming, chatter 
and general riding comfort. Make 
the adjustments in 2-click incre-
ments, then test ride. Repeat the 
adjustment 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 4 
clicks from the softest position.

• Turn the clicker clockwise for a 

stiffer ride.

• Turn the clicker counter-clockwise for a softer ride.
