Product detail

This is a single 4″ x 4″ go-kart axle hub with a 2-3/4″ hub length. Hubs sold individually. This hub uses a 1/4″ keyway slot. The 4″ x 4″ go-kart axle hub is most commonly found on go-karts using 8″ wheels. Although these hubs are incompatible with Yerf-Dog ‘karts, these are compatible with many quads, ATVs, and trikes that use this same hub. The hub features four lug nuts, and the hubs are 2-3/4″ long. The inner bore is milled for a 1/4″ axle key. The most common style for gokarts features a 1″ inner (or inboard) shaft diameter with the axle turned down to a 3/4″ outer diameter. Please note that our 4″ x 4″ Go-Kart Live Axle Hubs with 1″ to 3/4″ Step-Down are sold as singles. To complete your project, you may need to buy more than one. Specs are going to be important when selecting a new hub. Please refer to our following specs to see if this will be the right hub for your project.
