Traxxas TRX-4 1.9" Aluminium Wheel Upgrade ZSP049 by GPM  [ZSP049]

1.9" aluminium crawler wheels, 24pcs kit for builders

This aluminium wheel kit is engineered for 1.9" crawler builds and is supplied as a 24 piece set aimed at hobbyists and tuners. Aluminium construction gives stronger rims and extra mass compared with plastic alternatives, and a finished wheel weighs about 170g which can act as external ballast to influence crawl behaviour at low speeds.

The package includes metal wheel faces, rim halves, centre caps and flat head M2.5x7 screws for assembly, enabling the outer and inner rim sections to be secured with the provided fasteners. Wheels are intended for 12mm hex mounting found on many crawler platforms; confirm hex diameter and hub fitment before installation.

As part of a tuning plan these wheels replace fragile stock wheels and provide additional rotational inertia to help maintain momentum across obstacles. Installation uses a 12mm hex, appropriate torque on the M2.5 screws, and using thread locking where suitable to prevent hardware working loose during trail runs.

Ideal when you want a long lasting aluminium wheel set for 1.9" crawlers on 12mm hex hubs; remember to adjust suspension and gearing to account for the heavier rims.
