This GPM aluminium +1mm hex hub assembly is engineered as an RC-scale upgrade for the TRAXXAS 1/7 Unlimited Desert Racer PRO-SCALE 4X4-85076-4. The hubs interface with standard wheel hexes and front/rear wheel shafts to provide improved wheel seating and a measured increase in track width compared with the factory parts.
Construction notes mirror the source aesthetic: a metallic finish with swirl engraving on the outer ring and a deliberate hub width increase from 11mm to 12mm to widen wheeltrack. The kit supplies brake disks and 2.5x10.5 drive pins to complete the installation.
Installation is a direct-replacement procedure; align hex sizes, secure drive pins into the wheel shaft and confirm axial clearance before applying final torque. For best results inspect wheel balance and tread clearance after fitting.
