Track-Focused Details for XRAY 305921

The XRAY 305921 Narrow Pinion Gear targets drivers who need tight tolerances and steady operation in T4 series cars. Machined from aircraft-grade duraluminum, it is 1.5mm narrower and about 25% lighter than common pinions, lowering rotating mass while keeping strength.

Precision Machining for True Concentricity

Produced on XRAY's precision gear machines, this narrow pinion is manufactured to very close tolerances to deliver outstanding concentricity. Chamfered tooth edges plus a specialised hardcoat finish help the gear maintain shape and resist wear during repeated running.

Matched to XRAY Spur Gears for Smoother Drive

Made to complement XRAY spur gears, this pinion reduces throttle on/off chatter and improves overall driveline smoothness. It installs easily for racers refining gear mesh and noise without needing major setup changes.
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.

Which T4 variants work with the XRAY 305921 pinion?

The XRAY 305921 Narrow Pinion Gear is intended for T4 series models and is compatible with T4 2017 Specs and like-for-like variants that use the same pinion interface.

Can I pair this pinion with non XRAY spur gears?

Yes, the pinion can work with other spur gears provided the spur has a matching tooth profile and you set the correct gear mesh. Check tooth engagement and backlash before running.

How should I inspect and maintain the pinion?

Regularly check for burrs or wear on the teeth, keep the hardcoat clean of grit, and confirm gear mesh after hard hits. Light deburring and correct mesh will extend service life.
