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

Red anodised 2nd gear adaptor for NT1 gearboxes

This red aluminium 2nd gear adaptor is a scale replacement made for XRAY NT1 drivers who want a tougher gearbox part. It installs inside the NT1 transmission where the second gear needs a stable fixing point to maintain a steady mesh while running on track.

Built as a practical upgrade, the component emphasises consistent fitment and mechanical stability rather than bold performance claims. The aluminium body is less prone to deformation than plastic equivalents, which helps preserve spur and 2nd gear mesh under heavy use and frequent setup adjustments.

Installation notes: open the gearbox, remove the old 2nd gear adaptor using your standard NT1 service method, align the new adaptor with the gear stack, and secure it with the original bolts. After fitting, verify gear mesh and endplay. No special tooling is normally needed beyond typical NT1 maintenance gear.

Tuning use: this adaptor is intended as a straightforward metal swap to reduce lateral movement in the 2nd gear assembly during tuning, practice runs, or maintenance checks. It keeps gearbox geometry repeatable without altering gear ratios or central drivetrain behaviour.
