Modifying snowmobiles today is very different than a several years ago. Calibration, weight, power, and traction are all very good in mountain sleds right out of the crate. We spend hours and days testing to ensure expectations are met and—equally important—durability and reliability is maintained. We follow specific steps and procedures to improve performance. We do not approach this at random. As an example, why would you remove weight if you have not optimized maximum power transfer through clutches and gearing first. This is our way of making sure our customer gets the best bang for the buck!


We recommend clutching and gearing first for any mountain sled. With our clutching and gearing, it will accelerate, maintain track speed, and backshift much better then stock. Specific kits available for XP, XM & T3, G4 is work in progress.
