Front Hubs come ready to install on 3/4" or the more common 5/8" spindles. We carry many 3-bolt billet front hubs for racing go-karts repurposed for racing lawnmowers and recreational carts. We also produce dual pattern 4-bolt billet hubs for mini cup and other recreational machines that want to use larger 8", 10" or larger wheels.
Rear Hubs are made of billet aluminum and designed to fit on 3/4", 1-Inch, and 1-1/4 axles. We carry 3-bolt and 4-bolt rear hubs with identical hardware to our front hubs.
