Polaris Snowmobile Worlds Best Snow Belt Race Series
This belt is for the rider/racer looking for the latest technology and proven performance.

  • Build to decrease the chances of snapping or delamination in race applications when the tendency is to land on the throttle.
  • Manufacturing, quality control certifications – ISO-14001, ISO-9001, and IATF-16949.
  • Newly released design with a larger Kevlar cord and a custom braid design to act as a shock absorber.
  • New vulcanization process to marry the belt layers around the cord, preventing premature separation of the layers.
  • Custom blend of two premium High Modulus Compounds holding the top layers together with the cord and bottom layers like super glue!
  • Highest shock load rating to date, being able to withstand the power of the 600hp machines.
  • Increased top cog pressure load design increases sidewall rigidity, prevents top cog bowing, and increases rotational flexibility.
  • Bottom cog uses a HIGH modulus rubber compound (BZX1) for better heat resistance and dissipation.
  • Impregnated with short Aramid Fibers for better belt-to-sheave adhesion and reduced overall blet temperature.
  • Latest bottom cog design for greater rotational efficiency at full shift.
  • Precision ground sidewall angle (SCUFFING) for smooth engagement, increased power transfer, and lower operating belt temperature.
  • Kevlar cord, versus polyester, wraps over bottom cogs for increased bottom cog strength.
  • Increased cord pop-out resistance.
