Overview
Eliminate front-end flex and inconsistent steering on your Arrma 1/10 4x4 with the Hot Racing Aluminum Front C-Hubs (caster blocks). CNC-machined from 6061-T6 aluminum and finished in clean black anodizing with laser-etched lettering, this caster block set is dramatically stronger and stiffer than the stock plastic AR330442 caster blocks they replace.
Even better, the set includes metal kingpin bushings for smooth, slop-free steering pivot action — eliminating the bind and inconsistency that plagues plastic stock C-hubs under hard cornering loads. Also replaces the AR340138 flanged tube components.
