Moose Racing Aluminum Rear Sprocket - 47T - 1211-1439

The 7075 T-651 aluminum we use for these sprockets receives an extra tempering which reduces distortion and provides optimal thickness vs. typically thinner 7075 T-6 sprockets
100% machined, no stamping or grinding
Optimal tooth thickness results in maximum tooth and chain contact
We leave the cleaning grooves out of our sprockets, because more aluminum contacting your chain means longer chain and sprocket life
Moose Racing rear sprockets come anodized in black; select rear sprockets are available in red, orange and blue
Made in the USA
