This gun metal aluminum caster block hub set is an RC-scale replacement made for Element Enduro trail truck platforms. The alloy construction increases rigidity compared with molded blocks and alters steering geometry and suspension response for more predictable trail performance.
Fitting the hubs moves steering pivot points into a metal mounting, which helps maintain caster and toe settings during technical, slow-speed rock crawling. These parts are intended as a tuning item to evaluate how a stiffer front end changes steering feedback and component wear.
Installation is simple on chassis that use removable caster blocks: remove the stock pieces and fit the aluminum hubs using the existing mounting points, then confirm alignment and free steering travel. Recheck thread engagement and retorque fasteners after the first few runs to ensure proper fitment.
