Fine Tune a T4 2017 with the XRAY 305919 Pinion

When adjusting gearing on a T4 2017, the XRAY 305919 narrow pinion is a strong yet light choice. Made from aircraft duraluminum, it measures 1.5mm less in thickness and is about 25% lighter than standard pinions, reducing rotating inertia while keeping durability.

Engineered for Accurate Concentricity

Cut on a modified precision gear machine, this narrow pinion delivers exceptional concentricity. The manufacturing process includes chamfering all edges and applying a hardcoat finish to boost resistance to wear and preserve gear geometry.

Great Fitment and Reduced Gear Noise

This 19T pinion is compatible with common spur gears and pairs especially well with XRAY spur gears to minimise throttle on/off noise, giving a steadier, quieter drive.
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 shorten gear ratio using this pinion?

Swapping to a different tooth count changes overall ratio. This 19T option will alter ratio compared to other pinions, so calculate final gearing before running.

Does the narrow profile affect strength under load?

Despite the reduced thickness, the use of aircraft duraluminum and hardcoat treatment preserves strength for typical racing loads. Check mesh and alignment to avoid undue stress.

Should I change spur gear when fitting this pinion?

You do not have to change the spur if it is compatible, but matching to a high quality spur gear will yield the best noise reduction and mesh stability.

How often should I inspect the pinion?

Check the pinion for burrs, wear and secure fastening after a few runs and as part of routine maintenance. Early detection prevents larger issues.
