Polaris Axys RMK 850 Patriot Turbo Kit 2019-2022
Description
The Silber Turbo Polaris Axys RMK 850 Patriot Turbo Kit is a 3rd generation ECU reflash turbo system purpose-built for 2019-2022 Polaris Axys RMK 850 Patriot snowmobiles. Designed for riders who want serious turbocharged power without sacrificing the smooth, stock-like feel they're used to, this kit delivers performance that is equally at home on groomed trails or deep mountain terrain. Unlike piggyback fuel controllers, Silber directly reprograms the stock ECU - giving you precise fueling control across all riding conditions and elevations from sea level all the way to 13,000 feet.
At the heart of the system is a custom 2860 ceramic ball bearing turbo engineered specifically for small displacement, high-revving applications - it spools fast, stays cool, and holds up under the hardest pulls. A TurboSmart external wastegate gives you better boost control and easy adjustment, a feature normally reserved for kits at a much higher price point. If you've been looking for a complete, no-compromise turbo solution for your RMK 850 Patriot, this is it.
Key Features
- 3rd Generation ECU Reflash: Directly reprograms the stock ECU - no piggyback controller. Returns smooth, stock-like power delivery across all conditions. Fully reversible back to stock.
- 2860 Custom Ceramic Ball Bearing Turbo: Designed for small displacement racing applications - spools fast, runs cool, and built for durability through hard riding sessions.
- TurboSmart External Wastegate: Full external wastegate included for superior boost control and easy boost level adjustment - a major upgrade over internal wastegate setups.
- Wide Elevation Range: Engineered to perform from sea level up to 13,000+ feet with boost and octane adjustments for different altitudes.
- Adjustable Clutching Included: Everything you need to get on snow is in the box - including adjustable clutching for optimized power transfer.
- Intercooled Option Available: Available with or without an intercooler, letting you choose the setup that matches your riding style and climate.
- Silber-Specific Turbo Map: Every kit ships with a custom Silber turbo map - obtainable via reflash cable at home, a reflash center, or by sending in your ECU.
- Compatibility: Designed specifically for 2019-2022 Polaris Axys RMK 850 Patriot snowmobiles.
- Easy Installation: Installs in a matter of hours using common shop tools - no exotic equipment required.
Intercooled Options & Which to Choose
- Intercooled (Yes): Includes an intercooler for reduced charge air temperatures, which supports greater power potential and added reliability during long or aggressive runs. Best for riders pushing hard in warmer conditions or those who want maximum performance headroom from their turbo setup.
- Non-Intercooled (No): A streamlined, lighter configuration that still delivers impressive turbocharged power. Ideal for riders focused on a cleaner install, weight savings, or primarily riding in cold mountain environments where charge cooling is naturally assisted by ambient temps.
What's Included
- Silber 2860 custom ceramic ball bearing turbocharger
- TurboSmart external wastegate
- Adjustable clutching components
- Silber-specific turbo ECU map (reflash cable sold separately or ECU reflash service available)
- All hardware and components required for installation
Why You'll Love It
Silber Turbo has built a reputation in the snowmobile community for kits that simply work - reliable across elevations, smooth in power delivery, and backed by real engineering rather than off-the-shelf parts. The 3rd generation design reflects years of refinement, addressing every shortcoming riders have experienced with competing turbo systems. The direct ECU reflash approach means your sled responds naturally, with no surging or flat spots that piggyback systems are notorious for. Whether you're charging high-altitude mountain bowls or blasting through open fields, this kit is engineered to keep up without complaint. And when it's time to install, you won't need a specialized shop - most riders have their kits running in an afternoon. For RMK 850 Patriot owners who want more without sacrificing reliability, the Silber kit is the clear choice.
Do I need to send in my ECU to use this kit?
Not necessarily. You have three options: purchase a reflash cable and reflash the ECU yourself at home, visit a Silber reflash center, or mail your ECU to Silber for a professional reflash. The reflash cable is sold separately and gives you the most flexibility, including the ability to revert to the stock map if needed.
Can this kit be returned to stock if I want to sell my sled or remove the turbo?
Yes. The ECU reflash is fully reversible. You can flash the ECU back to the stock Polaris map at any time using the reflash cable, making it easy to restore your sled to factory condition.
Will this kit work at high elevations like mountain riding areas?
Absolutely. The Silber turbo kit is designed to function from sea level all the way up to 13,000 feet and beyond. You will need to adjust your boost level and octane rating based on elevation - detailed guidance is provided in the user manual included with the kit.
What is the difference between the intercooled and non-intercooled versions?
The intercooled version adds an intercooler to the system, which cools the compressed air before it enters the engine. This reduces intake temperatures, supports more consistent power, and can improve reliability during aggressive or extended riding. The non-intercooled version is simpler and lighter, and works well in cold riding environments where ambient air temperatures naturally help keep charge temps in check.
How difficult is the installation? Do I need a shop to install it?
The Silber kit is designed to be installed at home using common shop tools. Most riders complete the installation in a matter of hours. Silber also provides an install video and a detailed install manual to guide you through the process. If you need clutch and reflash tools, those are available separately.
