This is a set of two 17 mm metal wheel hex hubs made by Arrma as direct replacements for the stock plastic wheel hexes on compatible 1/10 scale 4×4 RC trucks. They are made from high‑quality aluminum and are precision manufactured so they fit easily onto your vehicle’s wheel hubs. These metal wheel hexes provide a stronger, more durable connection between the axle and the wheels compared with the original plastic parts, helping reduce wear and prevent stripping under load. The set includes two 17 mm aluminum hexes for installation.
