These sprockets start with a chromoly steel that is 10 times stronger then the OEM powdered metal, hot quenched with a low temper for the highest strength and resistance to wear.

  • All sprockets heat treated to maximum hardness while maintaining toughness

  • Precision CNC machined and broached for accurate fit

  • Dimensions checked after machining and after heat treating for guaranteed fit.

  • 80% more cross section versus OEM at the keyway

  • Weighs 30% more then OEM

  • High finish reduces friction and chain vibration

  • New tooth geometry strengthens teeth and keyway
