The 1-1/4″ x 40” Tubular Steel Axle is made of Chromoly and is keyed to the center, halfway on both sides. 

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

Axle Specs:

– 1-1/4 Diameter

– 40” Overall Length

– 0.190 Wall Thickness

– Offset keyways uses 1/4″ x 1/4″ Axle Keys

– Snap Ring Grooves

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.
