Traxxas TRX-4 Compatible 1.9" Aluminum Crawler Wheel Set ZSP048 by GPM  [ZSP048]

Precision 1.9" Aluminium Crawler Wheels

This aftermarket wheel set is engineered for 1.9" crawler tyres and 12mm hex hubs, built from machined aluminium to give dimensional stability and extra rotating mass useful for technical trail crawling. Notes in the source material call out measurable mass per wheel that can be used to bias vehicle balance and traction.

The supplied components for each wheel assembly include wheel disc 2pcs, outer rim 2pcs, inner rim 2pcs, center cap 2pcs, flat head screw M2.5x7 16pcs, providing all parts needed to build each unit using the included hardware.

Fitment and setup tips: these wheels are made to mate with common 12mm hex crawler hubs; verify your hub hex and wheel bore before fitting, ensure correct thread engagement on the M2.5 screws, and use appropriate torque to avoid stripping aluminium threads. The added mass helps lower the centre of gravity for slow-speed grip but can alter suspension response and steering feel.

Choose these wheels when you want durable, machined aluminium rims with deliberate rotating weight for scale-style crawling; confirm diameter and hex compatibility before buying.
