High-precision 18T first gear for XRAY NT1

Fit the Arrowmax AM-NT1-338518 to your XRAY NT1 for a precision 18T first gear crafted from 7075-T6 aluminium. It gives a good balance of lightness and toughness while maintaining accurate meshing with your vehicle's spur gear system.

Built to resist wear during competition

The hard-coated surface on the AM-NT1-338518 helps avoid rapid wear and keeps the tooth profile stable under sustained running. That reliability makes setup and lap-to-lap behaviour more predictable on race day.

Adjustable gearing options for track conditions

Available in a spread from 16T to 23T, Arrowmax pinions let you choose gearing tailored to specific circuits or driving preferences. Swap gears to prioritise quicker acceleration or higher top end as needed.
