Replacement slide rails for your 2022-2024 Polaris Matryx KHAOS 850, 9R, and 850 Patriot BOOST snowmobile suspension. All RMK and KHAOS models equipped with the Series 8, 2.75 lug track (or the 3.25") will use this rail. It is designed to use your factory rails tips and factory anti-stab kit for seamless integration with your factory extrovert driver setup. For 3" or 2.6" lug track equipped Matryx models, you will need our Axys RMK rails or Axys KHAOS rails according to your model. These rails will better integrate with your factory introvert drivers. Designed and machined from 7000 series aluminum with special attention paid to cutout design and location to create a stronger, more durable rail package than OEM. Classic rails are even lighter than OEM rails while being superior in strength. Bomber rails have fewer cutouts to create a much stronger, more durable rail that can withstand substantial abuse in the backcountry. We offer 146, 155, 163, and 165 variations. This allows you to shorten, lengthen or just beef up your existing skid length with the proven strength of IceAge Rails. Rails are pictured with our optional Matryx-specific 3" billet aluminum high strength 2 wheel anti-stab kit, but are directly compatible with the OEM 22-23 Polaris anti-stab kit and Matryx rail tips. Kit includes: 2 rails 2 hi-fax 2 idler adjuster housings, bolts, and mounting hardware Iceage decal ***Note*** Rails are cut to accommodate 8" rear idler wheels. Stock Polaris wheels are 7 1/4". Appropriate wheels are required for proper fit and function. Do not run the stock wheels on rails configured for larger wheels, damage to your track/rails/wheels may occur! You can find wheel options to install these rails on your sled HERE. 2024 RMK AND KHAOS MODELS YOU WILL NEED TO RUN OUR MATRYX-STYLE ANTI-STAB KIT AND 2x MATRYX RAIL TIPS FOR INSTALL TO REPLACE THE OE TIPLESS SETUP 165 rails and 163 rails are not interchangeable or cross-compatible. 153 tracks will not fit on 155 rails. NOTE: If you are installing this kit on a Matryx with factory introvert-style drivers, please purchase a Axys-style Khaos Rail kit. See chart below to identify if your Matryx has introvert drivers.
