Front Suspension Adjustments

Rebound Damping Force 
Adjustment

Increase the rebound damping 
force by turning the adjuster 
clockwise to increase the stiffness.

Decrease the rebound damping 
force by turning the adjuster 
counter-clockwise to increase the 
softness.

The maximum adjustment for this 
adjuster is the fully turned in 
position. The minimum 
adjustment is 16 clicks out from 
the maximum position.

CAUTION! Do not turn the adjuster past the minimum or maximum adjustment. 
The adjuster may be damaged.

Front Springs

For models without externally adjustable or revalvable shocks, the front 
springs can be changed if spring preload alone isn't sufficient and 
further adjustment is desired to control suspension stiffness. See your 
POLARIS dealer for more information.

THE PERFECT FIT

Rear Suspension Adjustments

The following information is provided only as a guideline to be used for 
initial suspension set-up. Your set-up may vary based on your desired 
riding style. 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 
the best performance for a given set of conditions. However, all 
suspension designs and adjustments involve a compromise, or trade-off. 
For example, a suspension set up for snow-cross racing would provide a 
very stiff ride on the trail. A suspension set up for trail riding would 
bottom out harshly on a snow-cross course.

Make adjustments 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 

preload should be set. However, this may vary with riding style. With 
a little experimentation, each rider can find a preferred setup. These 
adjustments are easy to make, involve very little time or effort, and 
greatly affect the ride.

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

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

TIP: Keep the suspension pivot points lubricated. This will reduce moisture and 

rust build-up and ensure proper function of the suspension components. 
Grease rear suspension pivots before adjusting the rear suspension. Refer 
to Suspension Maintenance beginning on page 92.

Track Tension

Track adjustment is critical for proper handling. Always maintain 
correct tension and alignment. Refer to the track tension maintenance 
section beginning on page 86.

Torsion Spring Tension

To adjust rear torsion spring tension, rotate the three-position cam using 
the engine spark plug tool. Different rate torsion springs are available if 
a firmer ride is desired. See your dealer for more information. 

Cam Adjustments

Soft Tension: Move the long end of the cam to the front.

Medium Tension: Move the short end of the cam upward.

Firm Tension: Move the long end of the cam upward.

Compression Damping

High Compression Damping 
Force Adjustment

Increase the high compression 
damping force by turning the 
adjuster clockwise to increase the 
stiffness.

Decrease the high compression 
damping force by turning the 
adjuster counter-clockwise to 
increase the softness.

The maximum adjustment for this 
adjuster is the fully turned in 
position. The minimum 
adjustment is 22 clicks out from 
the maximum position.

CAUTION! Do not turn the adjuster 
past the minimum or maximum 
adjustment. The adjuster may be 
damaged.
