XRAY 305991 precision narrow pinion

The XRAY 305991 Aluminum Narrow Pinion Gear is a 41-tooth, hardcoated pinion crafted for durable, low-mass operation. The aircraft-grade duraluminum body reduces turning weight so your driveline responds quicker under load.

Engineered tolerances for smooth meshing

Made on specialist gear machinery, the XRAY 305991 meets tight tolerance standards for excellent concentricity. The chamfers and consistent hardcoating help maintain steady gear contact and quieter operation, particularly with XRAY spurs.

Thin profile for improved drivetrain dynamics

Part of a 40T to 50T 64-pitch range, this 41T pinion is 1.5mm thinner and around 25% lighter than conventional gears. The slimmer profile reduces drivetrain drag and supports faster acceleration and efficient power transfer.
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 use the XRAY 305991 with aftermarket gearboxes?

Yes, provided the gearbox accepts a 64-pitch, 41T pinion and the bore matches your motor shaft. Measure shaft diameter and pitch first to confirm compatibility.

What benefits does the hardcoat give trackside?

Hardcoating helps resist wear from abrasive debris and maintains tooth profile longer, so you get consistent performance over many runs.

Should I change gear ratios when fitting this pinion?

The tooth count controls ratio. If you change to a different pinion size, recalc your gearing for desired top speed and acceleration, and check motor temps during testing.
