High-Precision 21T Pinion for XRAY T4 2017

The XRAY 305621 Pinion Gear is a finely finished 21-tooth, 48-pitch component intended for the T4 2017 line. Crafted from quality steel and produced on XRAY gear-making equipment, it keeps tooth geometry true for reliable drivetrain behaviour.

Durable Design with Smooth Running

Targeted at experienced RC drivers, this XRAY pinion features chamfered teeth and a run-in contour to promote even wear and smoother engagement. The rugged steel build and precise manufacturing make it suitable for repeated high-load use on the track.

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.

Can I swap this into older T4 models?

Compatibility depends on shaft diameter and spur gear spacing. While made for T4 2017, it can suit other versions if they share the same 48-pitch and shaft size; confirm measurements first.

What are the benefits of steel vs brass or aluminium?

Steel retains tooth shape under heavy loads better than softer metals, reducing wear and preserving mesh accuracy, which helps maintain consistent drivetrain performance over time.
