Axle diameter plays a crucial role in the stiffness and strength of an axle more often than wall thickness. As an example, our 1-1/4 axles are stiffer and stronger than solid 1" axles. The axle's stiffness also plays a role in the handling and specifically the rear grip of a racing go-kart or lawnmower. A stiffer axle will keep the rear tires planted, adding more grip. This is good for high-powered machines, but too much rear grip can cause the chassis to understeer(push), bind, or feel tight.
