THE PERFECT FIT

Suspension Adjustments

Factory settings, combined with user adjustments to the rear track shock 
spring (RTSS), should be all that’s necessary to provide the best riding 
experience for most riders. The primary adjustment for overall vehicle 
balance is RTSS preload. Perform this adjustment first.

NOTICE: Never adjust spring preload to an installed length longer than the 

maximum or shorter than the minimum lengths in the following chart. 
Damage to the suspension could result.

Suspension Adjustments

For riders who weigh 160-220 lbs. (73-100 kg), test ride at factory 
settings, then make fine-tuning adjustments. See page 44.

For riders outside the 160-220 lbs. (73-100 kg) weight range, adjust the 
factory-set preload to the following installed lengths as a starting point, 
then test ride before making fine-tuning adjustments. Do not exceed the 
minimum and maximum installed length requirements. See page 42.

TIP: If adjustments to the factory-installed springs are not sufficient for riders 

over 300 lbs. (136 kg), optional heavy springs are available. Please see 
your POLARIS dealer.

Suspension Adjustments

Fine-Tuning Your Suspension Set-Up

The primary adjustment for overall vehicle balance is RTSS preload. 
Adjust the factory-set preload to the recommended setting for your 
weight and then test ride. Additional minor adjustments can then be 
made to the spring preload to adjust the feel of the vehicle. Do not 
exceed the minimum and maximum installed length requirements. See 
page 42.

For more ski lift (transfer), reduce spring preload by increasing the 
installed length. Rotate the spring 1-2 full turns counter-clockwise 
(when viewed from bottom). This will enhance maneuverability, mak-
ing the snowmobile more “flickable” although it may hinder climbing 
performance.

For less ski lift (transfer), increase spring preload by reducing the 
installed length. Rotate the spring 1-2 full turns clockwise (when viewed 
from bottom). This will improve climbing ability and rider control.

To control the overall balance of the vehicle use the following guideline:

• More rear track shock spring preload increases ski pressure. Less pre-

load decreases ski pressure. 

• Spring preload can affect bottoming resistance. More preload means 

less bottoming. Less preload means a softer ride (and more bottom-
ing). Both adjustments will affect overall balance and ski pressure.

After adjusting RTSS preload to your satisfaction, the front track shock 
(FTS) spring preload and independent front suspension (IFS) spring pre-
load can also be adjusted. See page 46.
