This is a steel centre transmission gear made for the Axial Racing Wraith chassis and marked as part SWR038G from GPM. It is an aftermarket centre gear intended to transfer drive between gearbox sections in Wraith-style vehicles.
Built in steel as described in the product name, the unit is aimed at improved wear resistance compared with stock plastic alternatives. The part is supplied as a single replacement piece suitable for direct installation in compatible Wraith transmissions.
Fitment notes: disassemble the transmission to swap the centre gear safely, inspect shims and bearings for signs of wear, and reassemble with correct mesh and tightened fastenings to avoid placing extra load on adjacent drivetrain components. Using a steel centre gear can stabilise engagement under load while potentially increasing audible drivetrain noise.
