Radius Aluminum Spindle Spacer for 5/8 Spindle Axles. 

The Radius is made to match the radius on our EC Racing Lawnmower Spindles and many other racing go-kart-style front spindles. The radius prevents fracturing under stress made while cornering or under a load. The spindle spacers can set your track width on your front axle. The wheel spacing can change the handling and scrub radius of your kart or mower.
