How to Upgrade Your Ski-Doo Snowmobile’s Suspension and Handling


With the winter sports gaining popularity, people are moving towards biking, fishing and most commonly sledding. Riding a snowmobile in leisurely place or a smooth snow line is going to be a tiresome process if your suspensions are not aligned properly. The smoothness of the ride more or less depends upon the ride height. If you are also facing some kind of difficulty in enjoying your ski-doo ride, here are some of the tips how you can upgrade the suspension and handling.

Check the preload

The difference between spring’s free length and its installed length is called preload. Once the sled is off the ground, center shock-coil spring and ski can be checked. Set the preload to 5-10mm of compression.

Go ahead with limiter strap check

Make the front strap free of any tension by keeping the sled on a hard and smooth surface. Once this is done, the strap will cause even weight distribution throughout the suspension. The coupling system should be kept on an uncoupled position according to the owners menu.

Verifying weight distribution

A new snowmobile comes with handled weight distribution. However, Ski-Doo usagé noir can lose its equal distribution with time and you need to adjust them. The skidframe rails should rest flat on the hard surface. Use the limiter strap to bring about any changes if required.

Check free sag

The amount of compression in the suspension due to the weight of free-standing snowmobile is called free sag. Ideally it should be around 20 percent of sled’s total travel. Also, check if the sled is rapidly slamming to full extension while lifting the bumper. This process is called “top out. And you need to perform it for checking front and rear sag.

Lastly check the race sag

Once everything else is checked, the work is almost done. One last step that is left is of race sag which is the total amount of suspension caused by load applied to your vehicle. Adjust the torsion springs and make sure the coupler device is set in the middle level. Once the couplers are set in this position the rear end will be balanced with front end of the vehicle. Also know that this sag is done only for rear suspension since the loaded sag for front suspension is almost negligible.


By following this step by step guide you are sure to manage the suspension of your sled. Do these checks thoroughly and you are all set to enjoy these winters on your snowmobile.
