Lightweight Pinion for Sharper Response

For racers trimming every bit of rotating mass, the XRAY 305981 Narrow Pinion Gear provides a lightweight, accurate choice. Made from aircraft-grade duraluminium, it is 1.5mm narrower and around 25% lighter than typical pinions, helping the drivetrain spin up quicker.

Manufacture with Precision

XRAY use a specially adapted gear cutter to produce these pinions with excellent concentricity. Chamfered tooth edges ensure smooth engagement while the hardcoat treatment adds protection against wear.

Compatibility and Fitment

The narrow profile pairs well with many spur gears including XRAY's selections, preserving smooth throttle transitions and reducing gear noise. It ships ready to install for fast upgrades.
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.

Does the XRAY 305981 help top speed or acceleration more?

It primarily helps acceleration by lowering rotational inertia, though gains in top speed depend on the overall gear ratio and motor pairing.

Is backlash adjustment different with a narrow pinion?

Basic backlash setting is the same, but fine tuning may be beneficial to account for the slightly different tooth profile and to maintain quiet operation.

What maintenance should I perform?

Inspect the hardcoat for wear, verify concentric mounting on the motor shaft, and recheck mesh after a few runs to ensure long term reliability.
