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.

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.
