Machined from impact and wear resistant chromoly steel
Inner splines are broached to provide maximum spline-to-countershaft contact – this helps distribute driveline forces over the largest possible area
Heat-treated, then finished with a nickel coating for corrosion resistance and lubricity
BE SURE TO CHECK FOR CLEARANCE WHEN ORDERING SIZES LARGER THAN STOCK
Made in the U.S.A.
ALUMINUM REAR SPROCKETS
The 7075 T651 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 Moose Racing rear sprockets are available in blue, orange, and red
