• For high performance sleds, the top choice is the top-cog Ultimax Pro

  • The unique double cog design of our Ultimax Pro belt dissapates heat and aids flexibility

  • Cooler running belts - over 10 degrees cooler than flat-top designs - mean better performance snd longer lasting belts

  • Better flexibility cuts energy loss, allowing more horsepower transfer from the clutch to the secondary

  • Double cog Ultimax Pro belts feature a thicker cross section than flat top designs - more surface contacts the clutch, that means less slippage
    over a broad speed range for quicker acceleration

  • Exacting belt length tolerances minimize system wear and avoids excess slippage
