This aluminium adapter is produced for RC hobby use to couple a Z-series gear case with a ZX graphite upper deck when installing that deck on Z-series chassis. It functions as a precise mechanical spacer that lines up bolt holes and retains the intended separation between the case and deck without changing drivetrain geometry.
Finished from machined aluminium, the adapter delivers a stable mating face and aids consistent alignment during maintenance or component swaps. It is a structural mounting part and is neutral in terms of handling or tuning benefits.
Fitting tips: insert the adapter between the case and upper deck, align the existing holes, and fasten with your deck or case original screws. Inspect the assembly for correct alignment before applying final torque to avoid drivetrain binding.
