XRAY NT1 Spring Steel Engine Nut Upgrade - AM-NT1-330008 by Arrowmax  [AM-NT1-330008]

NT1 engine mount retention nut

This Arrowmax AM-NT1-330008 spring steel engine nut is an aftermarket retention piece designed for XRAY NT1 chassis engine mounts. It is intended to keep the engine assembly firmly in place during track use and maintenance, and does not imply any full sized vehicle application.

The nut is built to act as the locking clamp on NT1 engine mounts where a reliable retention element is required. Operators typically replace worn or rounded nuts with this spring steel unit to regain consistent clamping and lower the risk of loosening from vibration during racing.

During installation confirm the thread engagement and hand-tighten to seat the nut before final torqueing. Use proper RC tools and check compatibility with your XRAY NT1 mounting hardware; avoid forcing non-matching threads.
