This product was added to our catalog on June 2, 2015.This is an optional Exotek XB4 9° Aluminum Caster Hub Set. This heavy duty precision machined 7075 aluminum caster hub set is compatible with the full range of XB4 vehicles, and has been machined down to 6 grams per hub. That makes them incredibly lightweight, but much stronger than the stock plastic hubs. They match the stock geometry and still accommodates a set screw for the hinge pin. These hubs are polished, anodized and laser etched for easy left/right side identification.
