Guide to setting the rear suspension sag on your Ski‑Doo Snowmobile.
1- Before you begin, it’s important to park your snowmobile on a flat surface and remove the tether cord. Because you’ll want to take measurements while you sit on the sled, this process is much easier if you have a friend to help you.
2- Measure the height of your rear bumper before making any adjustments. Give the rear bumper a quick lift to fully extend the suspension. Pick a reference point (example: where the bumper meets the tunnel of the sled) and measure the height from the ground.
3- Next, with your friend holding the tape measure, sit on the sled and have them measure from the ground to the same reference point. The difference between the first and second measurement is your suspension sag. It’s recommended to have between 5 cm and 7.6 cm (2 in. and 3 in.) of sag for most Ski-Doo trail sleds. The recommended sag for most Ski-Doo deep-snow sleds is 6.5–10 cm (2.5–4 in.). The specific recommendation for your Ski-Doo model is found in your operator’s guide.
Ski-Doo Pro Tip: To get the most accurate reading, take your second measurement fully geared up. Wear your helmet, pack any accessories you need for a day of riding and fill your fuel caddy so you’re sure to account for all the added weight you typically carry.
