This aftermarket GPM wheel set is CNC machined from billet aluminium for tight tolerances and increased rigidity, intended for 1.9" crawler tyres on platforms using 12mm hex hubs. The manufacturing approach provides consistent dimensions and a defined rotating mass that can be used to alter vehicle weight distribution for technical crawling.
Kit contents are wheel disc 2pcs, outer rim 2pcs, inner rim 2pcs, center cap 2pcs, flat head screw M2.5x7 16pcs, enabling complete assembly of each wheel with the supplied fasteners.
Engineering and installation notes: ensure compatibility with 12mm hex hubs and confirm wheel bore dimensions prior to fitting, check thread engagement for the M2.5 screws and apply controlled torque to avoid stripping aluminium threads. The increased mass per wheel improves low-speed traction but will affect dynamic responses in acceleration and steering that should be compensated for in suspension setup.
Specified for builders seeking precision aluminium rims with known rotating mass for tuning scale crawlers; verify hex and diameter compatibility before installation.
