Speed up your snowmobile by lowering its weight and ensuring it has all its critical features set correctly (clutches, carbs, and track). Adding aftermarket performance parts to your vehicle is another option if you want it to perform better than stock. Learn more about the most incredible snowmobile performance upgrades and how to adjust these basic settings now that you’ve found us! Making sure a snowmobile is free of snow buildup and its systems are functioning correctly is the simplest and most cost-effective technique to increase its speed. Therefore, you must carefully inspect and adjust/fix the critical components of your sled to get the most out of it. Trying to figure out where to focus extra attention? Keep reading, and don’t stop!


If you want to make your snowmobile go quicker, the very first step is to clean its carburetors. The best course of action is to rebuild the system’s internals if you discover they are in poor condition. After cleaning and rebuilding, you must also configure the carburetors correctly. A properly tuned and jetted set of carburetors is required. To obtain the optimum possible fuel/air ratio out of your sled’s fuel injection system (EFI), ensure it’s been adequately mapped.


You should also be aware that poor clutch function or sheave buildup can often contribute to reduced performance. It is why clutches need to be checked and cleaned and, if necessary, rebuilt. It is to make sure they are working smoothly! Adjust the springs and weights, if necessary, to maintain a constant full-throttle revolution per minute (RPM). Be aware that clutch adjustment may necessitate several test drives and tweaks. It would help if you also inspected the drive belt in addition to the clutches. It should be cleaned or replaced if necessary, and its tension should be checked.

Gearing for the final drive (chaincase)

Many people don’t give final drive gears much thought when it comes to speeding up their snowmobiles. However, the sprockets in the chaincase can be replaced, which can lead to a more significant peak speed or better acceleration, depending on the size of the new gears. It is because these gears do the same role as the gears on a bicycle. Simply put, different sprocket always sizes equal varied performances. Don’t forget to adjust the clutches if you alter these gears.

Track, skis, and suspension are included in the package.

Keep an eye on the track if you can. Having an excessively tight or misaligned track may decrease top speed and cause severe track damage, so double-check both factors. Idler wheels’ bearings should be checked, as well as the hyfax slides (hyfax). Replacing the wheels with a “big wheel kit” can also help minimize the track’s drag and resistance. Changing the size of the truck drivers can also increase the speed of a snowmobile, which is a little-known fact. Don’t forget to align the skis and sharpen the carbides to get the most out of your skis. In addition, if you notice that your sled darts, you may want to fix it. Finally, it’s advised that you look into any suspensions. Strap limiters allow you to fine-tune the weight of your skis.

Performance Modifications for Snowmobile Snowmobiles

Ample Kit

Adding displacement to your engine is the most effective and safest approach to boost its performance. It entails adding a “big bore kit” to the engine or possibly swapping the entire engine for a larger one. Big bore kits are more popular than engine replacements since they are less expensive.

Turbochargers and superchargers

Installing a supercharger or turbocharger on a snowmobile is another typical approach to boost its performance. Compressed air is pushed into the engine by both of these devices, resulting in increased performance. Unlike a turbocharger, a supercharger is directly connected to the engine’s crankshaft, whereas a turbo is powered by exhaust gas. As a result, the “turbo lag” of the supercharger is eliminated. According to a general rule of thumb, superchargers are much easier to install and adjust than turbochargers. In addition to the higher fuel costs, these engines’ poorer dependability is a significant drawback.

Ensure your snowmobile’s engine, carburetors, clutches, and track are all working correctly before you try to increase its speed. If not, take care of them by cleaning, adjusting, or fixing them. If you are still dissatisfied with your sled’s top speed, you may want to consider making some modifications. Aftermarket items like big bore kits, turbochargers/superchargers, and so on are often installed during this phase. Even if you can’t afford to replace the entire engine, there are other options. Carbide/aftermarket skis, studs, modified running boards, or suspension improvements may be necessary for improved handling.
