The GPM differential housing is CNC machined from 7075 aluminum alloy to provide high tensile strength with low mass, delivering a robust upgrade for the Team Losi SUPER BAJA REY diff assembly. The component stabilizes internal gears and enhances heat dissipation under load while maintaining exacting fitment with original diff gears. A spacer is supplied to close tolerances and prevent deformation, removing the need for diff washer pads during assembly.
