Description

This 10 tooth jackshaft sprocket for the Hammerhead Off-Road® 80T and Mudhead® go-karts is used with size #40, #41, and 420 chain found on 20 & 30 Series torque converters. It uses the common 5/8″ bore (inside) diameter that matches up to the 5/8″ axle shafts on many popular models. This is a Type C sprocket where 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 3/16″ shaft key.
Note for Mudhead® owners: This sprocket is only compatible with Mudhead® go-karts without the reverse gearing.
