Traxxas TRX-4 1.9" Aluminium Crawler Wheels ZSP049 by GPM  [ZSP049]

1.9" aluminium wheel set - 24pcs for crawler builds

This 24 piece aluminium wheel set is designed for 1.9" crawler projects and suits builders who want stronger rims. The aluminium parts boost durability and add rotational weight compared to plastic wheels, with each assembled wheel weighing roughly 170g to act as ballast for low speed crawling scenarios.

Included are metal wheel discs, inner and outer rim components, centre caps and flat head M2.5x7 screws for assembly, allowing the rim halves to be bolted together with the supplied hardware. The wheels are made to mount on 12mm hex hubs that are common on crawler platforms; confirm your hub hex size before fitting.

These wheels play two practical roles: a sturdy replacement for fragile stock wheels and a way to increase rotational inertia for better momentum on obstacles. Fitment uses standard 12mm hex mounting, correct torque on the M2.5 fasteners and recommended use of thread locker to keep screws secure during trail use.

Select this aluminium wheel set for durable 1.9" crawler upgrades that use a 12mm hex, and adjust setup to suit the increased rim mass for predictable low speed handling.
