This 10 tooth jackshaft sprocket is used with size #40, #41, and 420 chain found on many go-kart and mini bikes. It uses the common 5/8" bore (inside) diameter that matches up to the 5/8" axle shafts on many popular models. In addition, this jackshaft sprocket is rather useful to the custom go-kart or mini bike builder who wants to design and assemble their own unique machine.

This is known as a Type C sprocket and the 5/8" thick hub is centered equally on both sides. (Type B sprockets have the hub offset to one side.) In addition, this sprocket is milled for a 7/32" shaft key.

Note: This jackshaft sprocket is not compatible with the Baja & Falcon mini bikes. These brands use sprockets with a slightly larger 0.675" internal diameter.
