Heavy Hitter Lightweight 420 Primary Chain Drive Conversion Kit

Important Notice: When installing, make sure your chain tension is not tight! Any chain drive that you install should have loose chain tension! Please check the fitment tab for important motor info. (MORE INFO HERE) The Heavy Hitter Primary Drive Conversion Kit was designed for those wide-open throttle riders who just keep snapping belts. Replacing a belt drive with a chain drive will lower the bike's efficiency, which in turn affects power delivery. Chain drives are stronger, just not as efficient. Heavy Hitter's goal with this chain drive is to give you maximum performance by providing the lightest kit on the market with the least amount of rotating mass!  After almost a year of iterations and updates to make this kit the best on the market for performance, yes, we have tested vulcanized rubber primary sprockets for noise reduction, but that significantly reduced performance. So this is what you get for the best kit on the market! Rear primary sprocket made from 7075 T6 Billet Alumin
