This aluminium 1st gear adaptor is a scale replacement item created for XRAY NT1 chassis drivetrains. Machined aluminium construction increases stiffness at the spur to pinion interface and helps ensure steady gear engagement for 1:10 electric on-road cars.
Engineered for NT1-spec layouts, the adaptor replaces factory plastic or alloy units as a direct-fit hop-up without changing gearbox arrangement. The red surface finish gives a quick visual reference during setup checks.
Fitting is aimed at experienced tuners: position the adaptor where the original part sat, secure with existing mounting points, check concentricity between motor pinion and spur gear, and fine-tune backlash and mesh during setup. The part is intended to aid alignment and geartrain tuning rather than modify the vehicle structure.
