The GPM AW1906SCYSBK is engineered with a focus on dimensional consistency and material resilience for scale crawler applications. These aluminium simulation wheels are specified for 4mm wheel shafts and 12mm hex hubs and accommodate 1.9" crawler tyres. Using a strong, elastic alloy formulation provides improved resistance to deformation under load, making them a reliable upgrade for rigs used in technical crawling and scale trail running.
