On a Snowmobile, Everything Starts With the Suspension System

Some will say the heart of a snowmobile lies in the engine. Personally, I say it’s in the suspension! When we look at the evolution of snowmobiles since the 2000s, it’s true that they have become more powerful. However, it’s really the introduction of the pyramidal chassis that had a major impact… something that is closely tied to suspension systems. Indeed, this system of moving components allows us to maintain control of the vehicle against all the physical forces and vibrations it reacts to. Without modern technology, riding a snowmobile would be very different from what we know today.
My goal with this article is not to dive deeply into the subject. Rather, I want to raise awareness about what I believe is the best investment you can make when purchasing a snowmobile. The shock package is a feature that many snowmobilers tend to underestimate.

Why are snowmobile suspensions so important?

Whether on groomed trails or in deep snow, from a technical standpoint a snowmobile is a mass of more than 500 lb moving through an environment filled with disturbances. We’re talking about bumps, holes, turns—and even you! The suspension system’s role is, therefore, to maintain the snowmobile’s stability. As a result, the vehicle becomes predictable and easy to ride in this constantly changing environment.

As an example, let’s go back in time and consider a post-pyramidal-chassis snowmobile. These systems once had a more limited range of motion. They were far less advanced than today’s designs. That was sufficient for riding at full speed on a perfectly groomed straightaway. However, the reality was very different in a section full of bumps.

Snowmobile Suspension: Better Trail Control and Energy Management

Quebec has more than 32,000 km of trails. You could easily ride from morning to night without ever taking the same route twice! Managing your energy therefore becomes important—and your suspension is definitely part of the equation.

A firmer suspension with better damping control allows for improved impact management. This way, you can ride comfortably and in control, while being better isolated from trail imperfections. Think about all the bumps and surface variations you may encounter during a 300 km day, for example. With a firmer setup, you’ll feel fewer of these variations, since they are absorbed by your suspension.

Think about it… Let’s assume, on average, one disturbance per kilometre. Your suspension will have absorbed close to 300 impacts over the course of the day. Every impact handled by your suspension is energy you didn’t have to expend yourself. The cumulative effect makes a huge difference by the end of the ride. Not to mention that, in addition to working less at every hit, you also reduce stress on your body, joints, and neck. For the snowmobiler who rides every weekend, a good suspension is a key element in achieving the best possible experience.

How a High-Performance Suspension Transforms the Ride

If I’m sharing this information with you, it’s because I’ve observed it firsthand. I tested two snowmobiles from the same brand that were relatively similar in order to compare their suspensions. The first was equipped with shocks featuring an external reservoir, while the second had monotube shocks, which are less performance-oriented. Within just a few kilometres, I immediately felt the difference.

Personally, once you’ve experienced this level of ride quality, there’s no going back. I’ve moved up to the next level. To illustrate the difference, what comes to mind is a train on rails. With the more advanced suspension, I found the snowmobile to be more planted. It held the line I set without flinching.

As a result, I felt a strong sense of confidence right from the start. I knew my snowmobile would respond to my inputs. In an unexpected tight turn, for example, the inside ski tends to stay on the ground much more easily. And bumpy sections have now become child’s play, since the snowmobile absorbs the impacts instead of my body.

In fact, since 2024, certain Ski-Doo X-package variants have been equipped with high-end KYB PRO 36 EA-3 shocks. In my opinion, this upgrade makes all the difference in handling. It translates into a smoother ride, where both small and large impacts are better absorbed. You feel fewer vibrations coming from the trail—it’s a bit like going from a Toyota Tercel to a Cadillac in terms of comfort. On the performance side, it’s like moving from a sedan to a coupe. In reality, the contrast isn’t quite that extreme, but understand that the difference is significant.

Suspension and Shocks: A Worthwhile Investment

Whether you’re a beginner or an expert, everyone benefits from riding with a high-performance suspension. The ride is more enjoyable, more engaging, and more dynamic—and at the end of the day, you have more energy left. How could you say no?
At the outset, I recommend investing right at the time of purchase in a model equipped with a premium shock package. We’re talking about shocks with an external reservoir. The reason for buying a snowmobile with high-performance shocks from the start is that it costs less than purchasing a base model and upgrading the shocks individually. That said, whether you buy new or used, the purchase price will be higher. On the other hand, it will generally retain better resale value. Then there’s the durability aspect. A high-end shock can allow for longer service intervals, since it typically runs cooler than a base model thanks to better internal temperature management.

Choosing the Right Snowmobile Suspension

In my opinion, your snowmobile’s suspension is a major factor in the quality of the days you’ll spend riding it. When purchasing a snowmobile, many people don’t see the benefit of paying more for shocks with an external reservoir. However, it’s once you’re out on the snow that the added value truly becomes apparent. The riding experience is far more rewarding, and you expend less energy controlling the machine. When you really think about it, can you name anything negative about having a good suspension? I challenge you.
