COMES IN A PAIR OF 2 WHEELS Some say you should not try to reinvent the wheel. We beg to differ! This is the solution we've all been waiting for. Our HELLFIRE wheel combines the tried and true strength of our billet Spitfire wheel with a new hybrid UHMW plastic outer ring for reduced weight, added serviceability, and most importantly the elimination of ice build-up issues. With thousands of miles of testing in varying conditions and terrain behind us, we can confidently affirm that HELLFIRE is the ideal combination of strength, bearing support, light weight, style, and user serviceability to make it the longest-lasting and most versatile option on the market.  Will not bolt on directly to stock polaris rmk/khaos rails, you will need the BIG WHEEL KIT w/ 7.25 to 9" offset axle to run HELLFIRE wheels on stock rails. 8" size is directly compatible with: - Polaris RMK/Khaos models 2006 to 2024 equipped with ICEAGE rails - Skidoo Summit 2013 to 2024 - LYNX 2022+ Boondocker and Shredder 146 (3700) or longer - Arctic cat twinrail mountain sleds 2012-2018 w/ the addition of our Arctic Cat Proclimb/Ascender wheel spacer , 2019+ models are compatible with the additional of our 2-wheel 1/2" slot axle - Yamaha Sidewinder M-TX Twinrail sleds 2013-2018 w/ the addition of our Arctic Cat Proclimb/Ascender wheel spacer , 2019+ models are compatible with the additional of our 2-wheel 1/2" slot axle KEY FEATURES: Reduced rotating mass from previous designs - (lighten your skid and increase throttle response) Ice-free UHMW outer ring User serviceable  Superb hub strength  Compatible with studded tracks!
