Polaris Axys RMK 850 Patriot Turbo Kit 2019-2022

$ 3,750.00

Due to material pricing and availability concerns we are changing up our snow check program a little to ensure you have your kits well before the snow flys. To secure todays pricing and ensure availability next winter we have already placed larger material orders than ever. This has helped us keep the price down but also means that we had to eliminate the traditional deposit program. We cannot take a deposit for something delivered 6 months from now given the current supply chain constraints. Snowchecked kits this season must be paid in full and will ship as soon as they are ready. This Snowcheck Program includes a free reflash cable and your kit will be delivered prior to Halloween. We expect to have many of the kits shipped and on your shelves this summer. Snowcheck pricing will remain active until May 23rd. All snow check kits are built to order and in the event of cancellation our standard 25% restocking fee will apply 

Those looking for clutch & reflash tools to be able to install the kit in your own garage you can find them here

    Buyer Information

    This is our 3rd generation ECU reflash kit and it does not disappoint. If you are looking for stock-like ridability with all the power of a turbo this is your kit. A few things set us apart from the competition.

    • Elevation: This kit will work from sea level to 13,000 feet (and up). However, you will have to adjust boost to fit certain elevations as well as alter octane. See the user manual for more information. 
    • ECU Reflash. No piggyback. We reprogram the stock ECU (don't worry you can flash it back to stock) to take control of the fueling demands for a turbo. This is why our kits run so smoothly across all elevations and riding conditions
    • 2860 Custom Turbo: Ceramic ball bearing turbo designed for small displacement racing applications. It spools fast, is very durable & stays cool during even the hardest pulls. 
    • External Wastegate: For the price of the "other guys" internal kit, you get a full TurboSmart external wastegate. This allows for better boost control and easy boost adjustment
    • Easy Install: Our kits install in a matter of hours using common shop tools
    • Everything you need to get on snow: Adjustable Clutching Included!
