Stock #40/420 Chain Sprockets

These sprockets are made of the same high quality 7075 T6 Hard Anodized Aluminum that we use with our RACE CLUTCH KITS, but will work with your stock clutch and chain. These sprockets require our QUICK CHANGE HUB, which allows you to change from one gear to another in less time. Teeth range from 26 to 43.
