These axles also have snap ring grooves on each end, as kart racing sanctioning bodies require.

Axle diameter plays a crucial role in the stiffness and strength of an axle more often than wall thickness. For example, our 1-1/4 axles are stiffer and more robust than solid 1" axles. The axle's stiffness also plays a role in the handling, 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.
