The GPM MJ012X axle housing assembly is manufactured from 6061 T6 aluminium and engineered to replace the original plastic housing on AXIAL SMT10 models. Its design focuses on improved structural integrity while maintaining correct gear engagement with the original AXIAL-SMT10 GRAVE DIGGER AX90055 gearset. The 4mm x 4mm screw hole pattern is provided to simplify oil filling and routine maintenance without removing the entire assembly. This component is intended as a strength and serviceability upgrade for demanding RC use.
