SMC Vortex BLACK Clutch Sprocket

The clutch sprockets that kart racers use today were invented by SMC about 16 years ago. Steel sprockets and drums use to be one assembly. These permanent assemblies retained heat, diminished performance and accelerated wear. SMC solved those problems with an aluminum drum that dissipates heat five times faster than steel. It allows your clutch to run cooler. Engagement is as effective on the last lap as it is on the first lap.

SMC engineers redesigned the sprockets and drums with a mechanical connection. Hard steel sprockets can now be attached to thermally efficient aluminum drums without welding.

SMC's sprockets offer a secondary benefit. Because they are easily installed and removed, it is no longer necessary to have an equal number of drums and sprockets. Changing gear ratios has become less expensive.

The 11 tooth #35 sprocket comes as a kit that includes the correct bushings for installation.

12 tooth #35 sprockets use a bronze bushing and require (optional) outside washer part number 4049.

13 tooth #35 sprockets use a bronze bushing and require (optional) outside washer part number 4023.

14-23 tooth #35 sprockets have a needle bearing installed.
