This is a pack of replacement Yokomo Graphite YZ-2 Molded Steering Hub Carriers. These are the front steering hub carrier for YZ-2 series.

These carriers feature graphite mixed resin for increased strength, improved steering response and crash resistance. On a high grip road surface such as carpet and artificial turf, the yore in cornering decreases, and the accuracy of the line trace also increases. By replacing the attached bushing, it is possible to set the height of the hub carrier (the angle of the suspension arm) to 5 stages.
