- 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
