Suspension Quick Set-Up Guide

Introduction

The front and rear suspensions on your AXYS snowmobile are easy to adjust. Just remember three simple steps:
  1. Ride your snowmobile.
  2. Adjust the rear track shock spring to tune vehicle balance (ski pressure and weight transfer).
  3. Adjust shock clickers (if equipped) to tune ride quality (stiffer or softer ride).
Step 1: Ride your snowmobile.
Ride the snowmobile in various terrain to fully experience the existing suspension settings before making any adjustments.
Step 2: Adjust the rear spring to tune vehicle balance.
After riding the snowmobile, you should be able to determine if the snowmobile needs more “bite” or needs to be more “lite”. If the steering needs more “bite”, increase the rear track spring preload or decrease the front track spring preload.
If you prefer your snowmobile has lighter steering, decrease the rear track spring preload or increase the front track shock spring preload.
At the front of the snowmobile, if you prefer a taller ride height, increase the front suspension shock spring preload settings. Likewise, if you prefer your snowmobile has a lower ride height, you can decrease the front suspension shock spring preload settings.
Step 3: Adjust shock clickers for ride quality.
You can adjust the shock clickers to control bottoming and adjust ride comfort. Turning a clicker counter-clockwise decreases damping for a softer ride. Turning a clicker clockwise increases damping for a stiffer ride and less bottoming.
NOTICE
Always adjust the clicker at least one click below full stiff (full clockwise) or shock damage will occur.
Test ride the snowmobile and continue making spring and clicker adjustments until you achieve the perfect ride.
NOTE
Adding traction components, such as traction studs or additional ski skag carbides, or changing the factory equipped track, could change handling characteristics. Addition setup may be required.

Rear Track Shock Air Pressure (SWITCHBACK ADVENTURE)

The factory-installed air assist rear shock contains zero air pressure, which will provide an optimum ride when combined rider and cargo weight is less than 200 lbs. (90.7 kg). If rider and cargo weight exceeds 200 lbs. (90.7 kg), use the following procedure to increase shock air pressure to the setting recommended for your combined rider and cargo weight.
NOTE
The shock air pump is located in the protective bag under the cargo rack.
  1. Remove the air valve cap from the shock.
  2. Thread the pump’s valve chuck onto the shock’s air valve until pressure registers on the gauge (approximately 6 turns).
    NOTICE

    Do not over-tighten as this will damage the chuck seal.
  3. Stroke the pump a few cycles. Pressure should increase slowly. If pressure increases rapidly, make sure the pump is properly fitted and tightened onto the air valve.
    NOTE

    If the shock has no air pressure, the gauge will not register pressure.
  4. Continue pumping to the desired pressure setting.
    NOTICE

    Do not exceed 50 PSI (345 kPa).
  5. To decrease pressure, push the black bleed valve button. When held partially depressed, air will escape steadily from the pump and shock. To make a micro-adjustment, press and release the button. Only a small amount of air will escape.
  6. Disconnect the pump from the shock.
    NOTE

    While disconnecting, the sound of air escaping is from the pump hose, not from the shock.
  7. Reinstall the air valve cap.

Do not exceed 50 PSI (345 kPa)

Limiter Strap Adjustment

The front torque arm limiter strap is set at position .

POLARIS recommends leaving the limiter strap length at position to maintain the optimum ride characteristics of the snowmobile. Riders who desire less ski pressure and more weight transfer toward the rear of the snowmobile can lengthen the limiter strap by changing to position .

Image
  1. Loosen the lock nut.
  2. Adjust the limiter strap.
  3. Tighten the lock nut.
