XRAY NT1 Aluminium 2nd Gear Adaptor XN1-05/RE by 3Racing  [XN1-05/RE]

Solid aluminium 2nd gear adaptor for NT1 transmissions

This aluminium 2nd gear adaptor is a scale RC replacement part made for XRAY NT1 chassis owners who want a robust, colour-coded gearbox component. Finished in red, the adaptor sits inside the NT1 transmission where the second gear interface needs a rigid mounting point to keep gear mesh consistent when the car is under load.

As an accessory focused on fit and stability, the part provides repeatable alignment rather than exaggerated performance claims. The aluminium construction resists compression and distortion compared with standard plastic adaptors, helping to preserve spur and 2nd gear mesh during hard driving and repeated setup changes.

Installation notes: remove the gearbox cover and the existing 2nd gear adaptor following your NT1 maintenance routine, check adaptor alignment with the gear stack, and tighten using the original fasteners. Re-check gear mesh and axial endplay after fitting. No special tools beyond your regular NT1 service kit are normally required.

Tuning role: fit this adaptor when you want a metal replacement to cut down on unwanted movement in the 2nd gear assembly during setup sessions, track testing, or routine servicing. It is intended as a direct parts swap to retain gearbox geometry rather than a part that changes gear ratios or drivetrain characteristics on its own.
