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

Racing-grade 2nd gear adaptor for NT1 tuning

This precision aluminium 2nd gear adaptor is engineered for XRAY NT1 users focused on consistent gearbox geometry and repeatable setup. The red machined adaptor provides a stiff interface for the 2nd gear, reducing elastic movement that can change mesh under high torque or hard impacts.

Designed with pragmatic performance in mind, the component improves mechanical stability and fitment repeatability without claiming to alter ratios. The aluminium structure resists deformation much better than plastic adaptors, which helps keep spur and 2nd gear engagement stable across multiple test runs and setup iterations.

Installation notes: follow standard NT1 gearbox removal procedures, replace the existing adaptor with the XN1-05/RE, verify alignment with the gear stack and secure using the original fasteners. After fitting, check mesh, endplay and free rotation under load. No specialised race tools are required for fitment.

Setup advice: use this adaptor when programme tuning or track testing demands consistent gear behaviour and less variation after impacts or adjustments. It serves as a precision replacement to lock in gearbox geometry rather than to change drivetrain ratios or primary behaviour.
