Maximize your torque! Please see the sprocket options below that will fit the QS MOTOR 138 70H 3000W BLDC Motor. These Amp sprockets were made specifically for this motor and come complete with a perfect fit galvanized C clip. All of our sprockets are made to last significantly longer that the standard finished bore sprockets on the market. This is acheived by use of hardened steel and galvanized coating to resist corrosion.
