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 100.

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-clock-

wise for a softer ride.

Front Track Shock Spring Preload

Increasing spring preload will decrease 

ski-to-ground pressure. Decreasing 

spring preload will increase ski-to-

ground pressure.
The initial preload setting is 1 1/4 inches 

(3.2 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.
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. 

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.
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 gen-

eral riding comfort. Make the adjust-

ments in 2-click increments, 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.
