The 4" x 4" go-kart axle hub is most commonly found on go-karts using 8 inch rear or front wheels. Although these hubs are incompatible with Yerf-Dog 'karts, these are compatible with many quad, ATV, cart, golf, and trike wheels that use this same hub. The hub assembly features a kit of 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 AlveyTech 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.
