Compact, accurate pinion for T4 2017 applications

The XRAY 305913 Narrow Pinion Gear is produced from aircraft-grade duraluminum to reduce width and mass while retaining tooth strength. Its 1.5mm reduced width and roughly 25% lighter weight help cut rotating inertia for crisper throttle transitions.

Controlled machining and protective finish

Each unit is cut on precision gear machinery, chamfered for smooth engagement and given a hardcoat to guard against wear. This combination yields quieter running and reliable meshing with XRAY spur gears.

Compatibility and handling improvements

Purpose-built for the XRAY T4 2017 series, the narrow pinion pairs with matching spurs to deliver stable power transfer and reduced drivetrain noise. The lighter pinion can also enhance transient response and overall handling balance.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Is the XRAY 305913 suitable for practice and race use?

Yes, the hardcoat and precise tooth profile make it durable enough for regular practice and race conditions, provided it is used with compatible spurs and correctly set up.

Will the narrower design change gear wear?

A slimmer pinion reduces mass and can lower heat build up, but correct mesh and alignment remain the biggest factors in avoiding uneven wear.

Should I pair this with an XRAY spur gear?

Using an XRAY spur gear is recommended for optimal tooth geometry match, though other compatible spurs can work if they share correct specifications and finish.
