RC Mission T4 rear hub upper blocks

Coming from RC Mission and made for the Xray T4 series of electric touring cars are the rear hub upper blocks, clever alloy caps that prevent the ball studs from breaking the hub in the event of a crash. The caps are machined from aluminium and they fit on top of the rear hubs, reinforcing the whole assembly and ensuring less stress on the single ball stud mounting position as the spare hole is filled with a grub screw. The caps can be flipped to use either the inner or outer ball stud mounting position and they are available as 2mm or 4mm variant, the latter resembling a setup with additional ball stud spacers.
